Racing the stripe if you have the lead

I know one thing for sure. Most of you guys either take bad weather info or no weather info. Every pass I make has temp, humidity, barometer reading, corrected alt, and sometimes Dew point. Headwind, tailwind if significant. Written within seconds of every pass and checked again as I leave for my next pass.
I do the weather checks as well. It's very easy to say make sure your car is consistent. Easier said than done, but if you are on a new build or tune it may not be consistent but you would still like to win the round, so once again back to the original question...
