(In reply to your message dated Thursday 21, September 1995) Rich et al I have worked pretty extensivley over the last 2 1/2 years with Kevin Gurr and have used Proplanner from the first day I started down the 'diving other gasses than air' road. My 2 cents........ Pro-Planner will allow you to put deep stops in anywhere you like. The programme just crunches numbers and produces a numerical result. What you need is the intuition to be able to decide what is a good protocol to follow. Whilst I do not follow what Rich does as regards adding deep stop time to bottom time as the entered bottom time I tend to put deep 'washout' stops from around 40m (130 ft) upwards when using trimix (usually on air or Eanx 32). Whilst this in pure number terms will reduce any mandatory stops it should be borne in mind I do not recommend that this be employed for the same reasons as most others - It works for me and I'm happy with the physiology. Propllanner is EXTREEMLY conservative on the inert gas calculations used for table production. There is a sotware switch that returns the defaults to the base figure (Removes the J factor). The comparative schedules are enough to make your hair stand on end!
