Vr3 for the dive,
cos it ant never let me down yet
it ant bent me to much
Zplan,
for working out gas need's for bailout cos its simple to use and play the numbers,
DDplan
back up and bailout tables , cos i like the print outs
Safety factors (padding)
Vr3 zero safety, may pad out last stop's if i think its been a hard dive ,,
up to one half the bottom max ,
zplan zero safety
ddplan set GF s to what ever come's in close to zplan numbers
ps
i have only dived to 90m and i may think about a 1.2 set point on bottom for dives past 100m,
when i do some
