For the typical recreational diving that I do, I'm an advocate for analyzing a nitrox fill once...with a properly calibrated analyzer...and then marking the tank with a clearly identifiable label indicating O2 percentage.
I've seen some people who have gone to the trouble of having their tanks O2-cleaned and festooning their tanks with nitrox stickers, yet they fail to mark their tanks with the analyzed O2 percentage and then flirt with the MOD of mix on their subsequent dive. That's pretty silly, if you ask me.
I've also seen people wearing 3 different dive computers who fail to do a comprehensive functional pre-dive test on their regulators/BCD or will continue to dive with a busted SPG. Human beings are funny.
Even for experienced divers, it's a good idea to periodically review your list of pre-dive checks to see whether any improvements can be made.
