Key things to record in your validation session are:

Range needs to be within 5m at 500m. 0.1 mrad click is 8m for me there. This is important if using a target board some distance out from the backstop behind or if the ground is curving and you can't range on the target itself.
Pressure. Most new phones have a barometer so get an app to display it.
Temp . Within 5C is enough
Slope if >10 degrees

Paper is better than gongs. Shoot 5 shot groups and measure in inches or cm. Best is to set sights for 100m and use a tall target so you aren't including scope adjustment error in your observations.

Put these into your app when back calculating your velocity and BC.
If possible get your G7 BC from Litz data.

It goes without saying that you have already standarddinsed your load and dont change components.
Barrel and batches of components can change a little over the years so check every now and then.

Then put in your estimated BC and MV and use the app to get a trajectory for conditions you will do the long range shots in. Often they are 1000m higher altitude and 10C colder than you do your trajectory test at. Day to day variation in barometric pressure is small but variation with altitude is very significant. Either use the ICAO atmosphere or just record the pressure on a few days hunting on the tops.
