great topic :thumbsup2:
Mullins says he thinks the ratio is 1.1:1 (horiz vs vertical), so in theory, if you can do a 100m dynamic, so you should be able to do a 45m dive HOWEVER there are lots of factor to consider
compensation:#1 limiting factor, such as being able to only dive to 32m because it is very difficult for me to compensate after that depth and my compensation technique is not very efficient.
finning effort: in a dyn swim, you have to keep a constant workload/speed to gain max benefits, but the force required to move this way is not close to what is needed to break the surface or come back from a deep negative position. there is the sink benefit and the the "float up" benefit at begin and end of dives.
If I could dive the same way in the same ratio as I swim, there is no doubt in mind I could reach 50m. Not that it is really a goal of mine. I train not for depth, but for bottom time.
the pros are doing 200m swims and 100m dives, sounds like the ratio works for them.
