I've been on 5x for a couple of months and the closest I've got to my weekly limits is 75%. I've hit 5-hr limits twice (expected). I'm a solo dev that uses CC anywhere from 8-12+ hr each day, 7 days a week. I've never experienced any of the issues others complain about other than the feeling that my sessions feel a little more rushed. I'd say that overall I have very dialed-in context management which includes: breaking work across sessions in atomic units, svelte claude.md/rules (sub 150 lines), periodic memory audit/cleanup, good pre-compact discipline, and a few great commands that I use to transfer knowledge effectively between sessions, without leaving a trailing pile of detritus. Some may say that this is exhaustive, but I don't find it much different than maintaining Agile discipline.

This being said, I know I'm an outlier.

Perhaps on the 10x plan.

It went through my $20 plan's session limit in 15 minutes, implementing two smallish features in an iOS app.

That was with the effort on auto.

It looks like full time work would require the 20x plan.
