Yeah I think it's cool, I used it instead of tables for my OW theory.
I cannot find how to enter the duration of the first dive. It tells me the NDL, but I cannot enter a shorter duration...
 
Hit enter again to get "ENTER ABT".
OK, thanks. Now it worked. My problem, as always, is that I hate those three-letter acronyms. I had no idea what was ABT ....

Lol yeah I'm pretty sure it's something bottom time, not sure about the A. Maybe absolute?
Oh it's in the Rules tab, ABT = Actual Bottom Time
 
Wheel gives an answer not there....
23 min because the SI credit to me is a letter higher as it is "on the line" - if I read it non-conservatively it is 24 min

Interesting link to the eRDP. Never used/played with one.... Actually, never seen one in use.
 
I ended up with 19 min but the 1min over the 30 min bottom time on the first dive put me into rep. group G I could have got another 4 minute bottom time on the first dive. Wouldn’t have planned that first dive to 31 minutes. It would be either 30 or 35 minutes bottom time by going 1 minute over I lost the 4 minutes surface credit.
P.S. US Navy Tables.

Then use the tab to see the acronyms...

I find it amusing that a dive to 21m for:
* 30 minutes equates to 30 minutes surface to surface.
* 31 minutes equates to 34 minutes surface to surface.

Yet PADI advertising states no decompression stop, so what is the mandatory safety stop?
