Average is about the best way of estimating.
You should care less about WOT settings unless that is the only way you fly, but then in that case you need a different turbine as it is powered incorrectly.

It is possible turbine A burns more at 100% RPM than turbine B but then turbine A burns less at 90% thrust than turbine B so how are you going to figure out what you need to know unless you have massive manuals of horrific looking charts.....oh yeah maybe you work for the FAA legal department.

If you are so concerned about fuel you should be asking for fuel charts for burn/thrust rates at every 1000 RPM, every temperature at those RPMs and lest we forget about every altitude at every RPM and every temperature...oh and then add in each possibility of humidity with each RPM, temperature, altitude etc...oh wait then what the difference in all those would be with Jet A versus Kerosene and then we could go on with each of those with each type of turbine oil...percentages of oil and then maybe even some numbers for 2 cycle oil.

forgot another one ...with and wihtout anti- static magic elixir for the purple ones.

For how much effort that would be on the part of the manufacturers and then add in the constant upgrades to service you can see it would be totally cost prohibitive in time and funds to produce such charts.

Asking for more is just being anal. Buy what is reliable, easy to get repaired if needed and makes you happy.

If you don't like the way the numbers are provided, buy the ones you are deciding on and then sell the ones you don't like....other than doing that you will never be happy.
