Fuel Planning
I was working with fuel planning to maximize payloads and loiter time, while using the charts in the -1 Specifically the cruising altitude chart I can't get the amount of recommended fuel to produce the cruise time it says it should. So to test this out I put an a-10 at 5000 feet and 300 knots. With 6 MK82 Air and 300 lbs fuel. In game I was able to fly 19nautical miles. Doing the math it should have been able to do 24.
I have checks the charts twice using drag index of 4 which is above actual calculated drag for weapon stores attached.
Either the sim uses a different rule for consumption rate and applies factors that effect distance traveled or I am using the chart incorrect.
It would be easy enough for me to just use what I know from testing fuel burn rates and make my own chart but I feel its skipping steps and it takes something from the fun of planning, I understand with the combat reserve and precautions taken with fuel planning that the 5 nautical mile may not be that big of a margin but 5 miles over a 150 mile trip adds up.
Does anyone have any tips for using the charts effectively or correctly?

It wouldn´t surprise me if the A-10C in DCS are consuming fuel differently compared to the real world A-10C. Charts are used as a hint of perfomance and getting an exact true value in different atmospherical conditions are impossible - there will always be some sort of difference between calculated perfomance and true perfomance.
The optimum cruise altitude chart (T.O. 1A-10A-1-1 figure A4-1) also doesn´t include any temperature and wind data, which have a great effect on engine perfomance.

so when planning for loiter time, would you plan a tank before checking on station to maximize loiter time, so you would not need to break station mid flight in order to tank and return?

That depends on the tasking. No pilot ever worried about having too much fuel remaining.

Only time you can have too much fuel is when your over max landing weight or on fire

I think he meant returning on station, not base.
