Just a "bragging rights" calculator... "My dive was a 1.27"... "that's nothin' -
my dive was a 1.3" While playing with that it dawned on me that I really did need to put some limits on a few things, and to add ways to accomodate some special situations, so now, while most "vacation recreational dives" (NDL dives over 15 minutes in reasonably warm water and reasonably good visibility) score between 1.00 - and 1.10, I've refined it a little to start down pretty rapidly for shallower and shorter than the 15/15 standard, but to give extra credit for extreme temps on either end of the spectrum.
I've also improved the ability to go back and correct mistakes by using the ESC key...
Have fun...
