Well, the random lynching and random targeting certainly leads to town doing worse than with human judgment. I think both percentages are significantly raised by this. The question is: which profits more from it? "Standard" profits mostly from lynches being directed by humans. But that is two-fold, as there is also scum trying to get a mislynch, so it's unclear how big this benefit actually is. The targeting of the town PRs might be the more significant factor. But since PRs live longer with the "No-Lynch" strategy, it might even be that this plan is stronger positively influenced.
Note also that both strategies do not include Cops claiming with a town result, as that is hard to implement. After all, there's no reason for scum not to fake-claim something here, and the program can't deal with fake claims. I think in the "No-Lynch" strategy, Cops shouldn't claim a town result, because it narrows down the kill pool for scum. In the "Standard" strategy however, they probably want to claim. So that would mean that there's a possible positive impact on the "Standard" strategy that I have not taken into account. But since the numbers are that far apart ("No-Lynch" being more than two times as effective as "Standard"), I do not think it swings the outcome in favor of "Standard".
