They should drop the rpm to slightly below 10500 rpm if that’s peak power and efficiency point because that would increase both average power and average efficiency.

For best average power they must be always at full fuel flow rpm range. For efficiency you might be right, it's more complicated.

I'd shit to a rpm slightly below that if the highest efficiency is at 10,500 rpm. Your maximizing the fuel flow times efficiency average over the shit-point rpm range. Not much below it, of course.

I think their situation is extremely complicated. First, they have a total fuel limit that dictates their strategy based on race conditions and race history. For example, rain, laps behind the safety car, etc. They also have the opportunity to send more heat and pressure to the turbo with late timing where the turbo can convert more energy into battery charge or directly into power at perhaps higher efficiency than the engine, depending on the power range, etc. This can especially be of advantage during harvesting when the engine is not providing thrust, but could use fuel to feed the turbo. Who knows the variations. It requires living with these systems to find all the tweaks. This is more than mind-boggling, it looks like a field day for the truly clever guys and girls.

That would be when you romp on the lever, get first instead of third and scream "OH SHIFT!! ?

Maybe it was a Freudian slip on a turd sitting on a can typing the message on an iphone?

To demonstrate how fast a thread can go off the rails: yesterday I was watching the Dr. Oz show. He was discussing stats on the use of phones on the John. Over 60% of those polled used them there. Their average throne-time was 40 min. of alone time vs. 5 for the non-multitaskers. He also had the devices of 50 'phone throners' and 50 'nons' swabbed for coli-form bacteria. The recommended maximum count is 10. The 'nons' averaged 30, which is actually pretty good. The throners weighed in at 106,000....

I got a laugh out of that, not sure if it was the 106,000 count or how far off the rails premise was actually taken.
