Hikaru and Chessbrah are playing at GM level. It'd be difficult to cheat at this level. Every player tends to recognise every other player, and it takes time to climb to this elo. A far more representative example would be to observe games from a NM or IM. These guys often bump into cheaters. 1 in 6/7 isn't unrealistic.

Not always. Hikaru does speedruns[1] using an alt acct with entry-level ELO to race to ELO 3000. I've watched a fair bit of this, and seen him encounter the odd cheater or suspect game, but much nearer 1% than 10% of the time.

I don't disagree with what you said, but for context: when these players do speedruns they typically start from 600 ELO and work their way back up to GM, so they face players at every level as part of that 100-game streak.
