Why was my actual run time longer than the original plan
I have a basic understanding of GF's and m-values, but i guess i don't completely understand the difference in run times when different GF's are used, and all the contributing factors.
Here is my example and the dive that caused me to pose this question. Plan was a 200ft dive for 30min on ccr. My buddy was diving a meg and runs his ppo2 at 1.3 during the dive and 1.4 at deco, he has a pursuit set at GF 10/90. I am on a rEvo and run at ppo2 1.2 for the dive (manual) and 1.4 for deco, and a predator set at GF 25/85.
If i run this plan in my predator it gives me a run time of 90 minutes. with my first stop at 100ft. My buddy's plan gave him a stop at 120ft. I of course stayed with him. This caused me to reach each stop later than originally planned and by the time i got to my shallow stops they were significantly longer than the plan: plan 20ft for 11 min; actual 20ft for 15 minutes; plan 10ft for 19 min; actual 10ft for 25 min. The end result was that it took me 110 minutes to get out of the water instead of 90.
Is this longer run time due to me being penalized for the deeper stops not in my plan according to the GF i was running vs my buddy? Is the 0.1 difference in pp02 creating such a difference? If not can someone explain why the longer run time.
