It is correct you can start DM with 20 dives and DRAM rescue. Does not mean you will or be allowed to.
Would I allow someone to do that? Nope, no way. First of all I don't need a DM most of the time, my classes are small so they would not get much practice, and so why even bring it up?
The instructor has full discretion over this. In my experience I have seen instructors turn away DM students more often than not. Since most of the SEI instructors are independent and don't do this for a living we are not interested in turning out a bunch of DM's. There just is not the need for them so why push it. Master Diver is a much more popular and frankly useful cert for the majority of our students.
But as this thread is about rescue skills the reason we teach panicked diver, unconscious diver, supporting a diver at the surface and helping them get positive, and rescue tow while stripping gear is becasue these are the skills they are most likely to require as open water divers.
As for doing all skills on one dive, sure. Why not? These are not teaching dives. The checkouts are to evaluate that the student has had the training to dive independently and has all the skills necessary. They are supposed to be fully qualified to do this once the pool training is over. If we feel that doing all the skills on one dive is too much for them then we can't take them to open water. They are not ready. The philosophy behind our training is so foreign to some that they can't seem to grasp it. We do not train people to come back for more training.
In fact just the opposite. Every SEI OW diver is technically certified to what we refer to as the Sport Diving limit of 100 feet right out of the OW class. They are given all the tools, including rescue and emergency decompression table use, to do this. It is advised that they work up to the max depth but they are not required to come back for Advanced Level or specialty training should they choose not to.
I would dive to 100 ft with an SEI OW diver that has never taken the Advanced Level classes because I know they have the skills and knowledge to go there. They have been trained in gas management, dive planning, and would be able to save my butt if something happened. I know this because they would not have a card if they could not. Neutral buoyancy is required and taught.
I have OW students I've trained that are better in the water than some of the DM's I have seen at local training sites. Because they are required to be. I know a number of the SEI Instructors in the US. None that I know teach to the minimums. Everyone adds material to their courses and tests on it to suit their local conditions, their own experiences, and the stuff they feel their students should have. Not just because they want to but because they are required to by standards. Exceeding the standards is a standard.

If SEI requires 10 minimum logged dives, then sure, we can include those in the comparison. Guesstimate $80-800 for that then.
So added costs to take rescue gets closer to each other but it seems SEI OW still provides more rescue training as part of the standard package.
Does SEI require first aid also?
General first aid and water related first aid is part of the OW course. Is it as in depth as say a Red Cross Course? No. Unless the instructor is a Red Cross, AHA, or DAN instructor and wants to make it part of it.
