If someone's OTB rating is 1700 & their RHP rating is 2300, they are using an engine. No doubt; and not worth arguing about.
If someone's OTB rating is 2000 & their RHP rating is 2300, they are using an engine. No real doubt; and not really worth arguing about.
If someone's OTB rating is 2100 & their RHP rating is 2300, they aren't necessarily using an engine.
Anyone 2400+ at any point is using an engine. No doubt; not worth arguing about
Anyone whose RHP rating rises, after the first performance plateau has been reached, by more than 200 is using an engine to achieve that improvement.
For the record, my OTB Elo is 2100 these days, down from my peak at 2280. My ICCF rating (from 2001) is 2201, down from 2350 in 1992, and from 2450 in 1982. Engines have caused the recent decline; family/career, the earlier fall.
