</div>Change the timestep used to calculate tissue pressures and ascents from 3 seconds to 2 seconds.  But whats wrong with using 3 seconds?

Deco stops are at 3 m (10') intervals, and our ascent rate is usually 9 m/s (30'/s), or at least multiples of 3 m/s (10'/s).  Hence time to ascend from one stop to the next stop is 20 s (or any factor of 60).  Using 3 s increments, we round our ascent interval up to 21 s, which leads to messy durations and runtimes.

But what about me?  I like SI units and whole decimals.  Don't worry, 2 s timesteps fit nicely when using 10 m/s ascent rate (18 s between stops).
----------
Back in college m/s was meters per second.  Its been nearly a half century since then.  But I suspect this ascent will work out about  third of a mile per minute.   This is just off the top of my head so I could be all wet.  But no diving today so can't blame that for being wet.
