Some of the people on the list design decompression software and are 100% up on the tissue half life algorithems. Funny gas mixes etc so will be able to tell you about breathing nitrox to help etc.
Biggest problem with deco is it is all based on statistcal curves and there are quite alot of cases of people getting bent inside the tables.
And if it helps I have dived similar profiles and we drove back over the Rest and be Thankful which is well over 1000ft with no probs felt. This dosn't mean I didn't get a brain bend which most pilots get at some point in their career but can't feel it.
Which is why commercial divers always play safe and want to stay as low as possible
