Hello,
I own a Petrel, and think it's a great computer. I've been doing some experimentation with GFs lately in an effort to move my diving profiles more toward the ZHL-16C algorithm and away from a deeper stop bias. To do so, I'm modifying the GF lo to a higher setting, but I'm running into a few restrictions in the Petrel that are causing me problems.
First, if you set GF lo higher than 50%, then the max the GF hi can be is 90%. This isn't a huge problem, but I may want to run my computer at max ZHL-16C (100/100) for contingencies (or even 95/95 to be less on the bleeding edge), and then just cut more conservative tables. I would like to have that option, but currently do not based on the Petrel's restrictions.
Second, I am not able to have a GF lo that is higher than my GF hi. For example, I cannot produce an 80/70 profile. I see value in this type of profile as I can stick more closely with ZHL-16C during the ascent and first stop, but then introduce additional conservatism along my shallow stops. I have a piece of software than can produce these tables, but I would like to be able to run a profile like this on my excellent, highly capable deco computer as well.
Outside of posting here, is there a way to get this request considered?
Thanks,
Mike Guerrero
