How long is slow burn to you?

Okay so I'm old... well technically middle aged but that's old to some. When I think slow burn, i think 10+ chapters (or at least 15k words) of me basically screaming at the majority of the story for them to hurry up already. When I think of really really slow burn i think this is 20+ chapters (or at least 50k words). However, over the years I've seen slow burn attributed to 5k words and less. All are complete stories, and most are amazing stories but it just gets me wondering. Has the length of "slow burn" changed and I missed it? I'm legit wondering 😅
