Significant fuel burn discrepancy at FL200-FL240
-
Today at FL200 and FL240 I expirienced a massive fuel burn discrepancy compared to the POH of Rob Scheerer. This is for maximum range cruise. For recommended cruise the figures are much closer and withing the usual 5-10% I usually experience with Starship.

What sim version are you on? Your IOAT is about ISA+5. In your 20,000 foot case, your CDU shows closer to 12000 lbs not 13000. Looking at your data and iterpolating for ISA+5 at 12,000lbs and 20,000feet I show The following: IOAT 13C, Torque: 44%-45%, FF/Eng 299lbs/hr, total 598lbs/hr, IAS 178, TAS 243.

@Mad_X Check out item 3 of a write up I've made a few months back.
It's almost identical I believe as yours. But the funny thing is, my fuel used did agree with the tables. Just not the indication. Have a look at item 3 of my post and try to do the same. Doesn't need to be as complex. You can take remaining fuel at the start, then (leaving power constant) take another reading 15 minutes later. That difference in fuel remaining, multiply it by 4 to get your 2-engine fuel burn in pounds/hour. Divide that by 2, and you get the average engine fuel flow. That value should match the fuel flow indicator (and also your tables).
For me, it matched the tables, but not the indicator. As you can see from my post, I didn't hear anything back other than that it should work normally.
