Anyway, I haven't cracked it yet. The best I can figure is that the larger numbers(52, 37, 27, 18) are figures for a specific botom time. The smaller numbers(2,6,7,2) are decompression times for the afore mentioned bottom times. What I can't figure out, are at what depth do these figures apply. Also, I'm wondering if the placement of the numbers on the dial are really relevant, or are they just convenient places to place them.
I'm not giving up though. If we keep at it, I know we can figure it out.
