Man, if you can't do this in your head at your desk, perhaps you had better not
be diving...

The curious thing is that your number is so random -- I could see if you came up
with 270 fsw = 2.0ppO2 on air (30fsw X 2.0ata / .2ata - 30fsw ==> easily done
in your head quickly), but how did you get 257fsw???

(Appologies for flaming, but really!  This is essential stuff, and should be
down cold!)
