I know you get paid more after 1000 submissions on Mturk, but are those better-paying ones also longer?

I've been nearly exclusively with Prolific for a bit, and prior, I was on Usertesting. I know a lot of people make some pretty decent money on MTurk after some grinding, but do those higher-paying gigs also come with the caveat of being longer? With Prolific, in general, most better-paying gigs are 20+ minutes - which is fine. I'm just curious what I should expect out of MTurk after grinding.
