None of the reasons you wrote are nearly as reasonable as your boss(es) seeing you as a reasonable person, a team player, etc. as evidenced by your open discussions. Some things they can't glean just from the fact that you solved a ticket quickly.

Yours looks more like a list of ridiculous, implausible but of course still technically possible reasons. As a boss I'd like to know if the person I'm promoting is willing to come up with such arguments in an attempt to prove a point. ;)
