Does canceling a queue and then re-queuing help at all?

But you're dealing with strictly anecdotal evidence.

For example: JUST NOW AS I WAS TYPING - I got an "in progress queue" pop after 14 minutes in queue. By your theory, 14 minutes now becomes a magical number for in progress queuing. Because it happened to me and I noticed it.

You're not keeping track of data over a period of time. You're remembering specific instances that agree with your theory. That's what confirmation bias is.

Said it best right here. Someone start a data page.
