had a few hickups on 2 dives where the program failed to compute the residual nitrogen. 1st dive 18 ft for 21 min. end presure group "C", SI of 1:10 presure group "A" 2nd dive 15 ft for 31 min final presure group "H". The App figured the 2nd with a final preasure group of "E" it failed to add the residual nitrogen of 10 to the actual bottom time.
