Yeah ... paid a little closer attention to the spinning while reviving thing ... pure illusion.
I checked doing it with the drill, too. But we rarely need to repair the drill so I don't know how reliable the test was. I start repairing without spinning and it was going slow. About half way through, I started spinning and, at first, it did not seem to be doing it any faster. When I looked up to the sky - mind you, I don't use 420 or anything - but I swear the bar started moving faster. But the drill was nearly repaired by that point anyway so ... I dunno. Feels like revives and repairs are faster when you spin. Plus, I always run the riot shield so there's somewhat of a protective measure in doing it.
