Hello, I always was flying for several years at 100% RPM, and never wondering why the range is so low. I've spent many hours doing tests, and came to conclusion, that if taking typical SEAD loadout, it is the best to keep RPM at 93% when going at altitude 2000m. Interesting thing is, that going slower than like 90% is also making flying less efficient. Here is the excel file I made, maybe someone will find it useful.
