Why 1% risk with a "prop firm" doesn't work, and will doom you to failure.
But it can work if you're self-funded. Here's the thing; I, personally, risk 0.1% with "prop firms" because the accounts are free anyway. They refund when you pass and you have unlimited time to pass, so the entire goal becomes keep the account as I can always get more accounts. I'd rather trade 0.1% of the account with a risk of ruin that's basically non-existent, vs trading 1% of the account and basically guaranteeing that I hit max drawdown as inevitably there will be a 5+ trade losing streak.
That's the key issue almost everyone misses, risk of ruin.
The whole 1% recommendation is for self-funded accounts, not "prop firm" accounts. If you have a self-funded account for $100,000 and risk 1% you can get it
