This makes sense. I like the idea of adding 1 minute every 12,5 minutes for 
this though I would like to have the ability to switch it off. We cold 
water dives _may_ be subjected to 'worse' deco due to cold.

But then again, a 1% change in the gas shouldn't make too much of a 
difference deco-wise. We're talking an mathematical 'model' of our very 
complex body.

ZPlan will give you times in seconds.

Agreed but it'd be nice to be able to switch it off.

Aren't you in the UK? Isn't it enough to write 'evaluation purposes only'?
