I am not convinced that the majority of experiential divers would care even if they were informed of the difference. they don't plan on diving frequently so why put the time, effort, and money in to do so.

I would disagree with the 99% roughly the same time (on schedule). Perhaps 20 years ago.Well, sure. People choose the cheapest airline ticket from the major US airlines with justifiable confidence that what they are trading is money for comfort and time, as their safety is pretty much a given no matter what they choose. All major US airlines are incredibly safe, if you get on the plane you will get off the plane, and 99.99% of the time it will be where you expected to get off the plane and 99% at roughly the time when you expected to get off the plane.
I am not at all sure non-divers understand the implications of their choices of dive training. They are not all comparably assured of the outcome, and the agencies see to make a lot of effort to ensure that non-divers cannot easily determine that there is a difference.
Kinda, but you have to have the know-how to actually work on your car as well. I dive with plenty of people who can tell me if their first stage is leaking, and some who could even tell where it's likely leaking from, but I don't know a ton of recreational divers who know their regulators well enough to actually fix them.
That, and factor in that something like ALLDATA costs a couple hundred bucks a month, and car maintenance is still super expensive, unless you really know what you're doing.
Not just that, but what tthis has shown the majority of customers will prioritize cheap over good. It’s a race to the bottom because that’s what ‘the market’ wants.

Parsing?I was trying to say I have difficulties parsing that.

OK, took me a while to find it but here is what we worked out of.
PADI Open Water Manual c 1990 - 1995
Version 1.0
Product No. 70011N (table version)
This is the skills portion only.
Swim test - 200 yards free swim in pool no time limit and any swim style
400 yards mask fins snorkel swim
Module one;
1. Scuba equipment assembly
2. Equipment prep
3. Donning equipment
4. BCD inflation / deflation
5. Introduction to scuba
6 Regulator clearing
7. Regulator recovery
8. Mask Clearing
9. Use of fins
10. Neutral buoyancy at surface
11. Equalization and underwater swimming
12. Descending under water
13. Ascending
14. exiting the water
Module two:
1. predive safety chack
2. controlled seated and giant stride entry
3. snorkel breathing and clearing
4. Snorkel regulator exchanges
5. No mask breathing
6. Mask replacement underwater
7. Proper weighting
8. Surface snorkel
9. Cramp removal
10. Tired diver tow
11. deep water exit
Module three:
1. No mask swimming underwater no less than a distance of 50 feet
2. Neutral buoyancy underwater
3. Use of alternate air source
4. Free flow regulator breathing
5. Controlled emergency swimming ascent - travelling sideways no less than 30 feet while exhaling saying "ahhh".
Module 4:
Proper breathe up for skin diving
Perform a headfirst skin dive down (pike)
Clear and breathe from snorkel upon ascent
Buddy breathe sharing a single air source for a distance of at least 50 feet underwater as both a donor and reciever.
Module 5:
1. Remove, replace, adjust, and secure scuba unit and weights at the surface with minimal assistance in water too deep to stand up in.
2. remove, re[place, adjust scuba unit and weights underwater on the bottom with minimal assistance.
3 React appropriately to air depletion by giving OOA signal - share air.
Open water portion in ocean;
Dive 1.
1. Briefing
2. suit up (no scuba)
3. entry
4. predive acclimation (skin dive)
5. Buoyancy check and adjust
then..
6. Don tank and weights
7. BWRAF
Then entry, buoyancy check, controlled descent, fin pivot, reg recovery and clear, clear partially flooded mask, Alternate air source use stationary.
Dive 2.
Equip check
Cramp removal self and buddy
25 yard tired diver tow
Free descent with reference
Buoyancy control
Complete flood and clearing of mask
Alternate air source assisted ascent
Dive three:
Perform a skin dive and show proper use of snorkel (20 feet in my class)
Proper descent and ascent techniques
Surface swim (kelp crawl in my area)
Underwater swimming with buddies alternate
Dive 4 performance requirements:
50 yard surface swim in a straight line with compass ( diver A out - diver B back)
Snorkel regulator exchange
Free descent without reference to a depth no greater than 60 feet.
Buoyancy conrol - neutral on bottom.
Clear flooded mask
Buddy breathing off one regulator stationary at depth
Buddy breathing off one regulator ascend to surface
Remove/replace scuba unit on surface
Dive 5 performance requirements:
Free descent with no reference to a depth no greater than 60'.
Perform navigation swim underwater (out and back each buddy)
Remove and replace mask underwater
Achieve neutral buoyancy underwater and hover in mid water without swimming.
I guess we did do 5 dives? I couldn't remember.
Seems to me I also remember rolling a weight belt on on the surface and underwater but I can't find it in the manual? It seems I also remember doing a CESA in the ocean with reg in mouth with buddy then trading.
Then there was learning the tables forward and backwards, Pages 195-214.
This was 4 long days, two full weekends. I think there was 8 of us students, plus the instructor, one AI, and two DM's in training.
Hope this helps. I have no idea what they do now days, you know way more than I do.
All I know is there would be no way to do all this in 3 days. My instructor was also an ex Navy guy, Navy Diver. He made sure everybody was thorough with their skills before we hit the ocean because he wanted all of us to pass and he didn't believe in skimping on instruction or letting anybody by easy. He even told us it was going to be that way and our course was going to more than what you would get at a vacation spot (his words). And if anybody was not OK with that they could leave then and they would be refunded their money before the class started.. He did not believe he was doing anybody any favors by letting them through with out doing everything correctly and thoroughly if they were going to be diving on the north coast. Instructor Jerry Meyer MSDT-96801
The next weekend after the class a buddy and I went out and conducted a beach dive on our own at a local beach in 48 degree water with rocks and surf, had a blast. The weekend after that I was on a charter boat in Monterey with the same buddy doing a wall dive at Point Lobos in 95 feet of water using our new shiny tables and loving it!
Nobody drilled into our heads that we were only supposed to go to 60' or we would get our hands slapped, they kind of minimized that part.
But that was then.
