How fast can you pull U with your right index finger 20 times in a row (five times U4)? No index+middle finger tricks or continuous rotation, just 20 individual index finger pulls. Post your exact time below and vote in the above poll I'll add in a moment. I'm looking for your best, so you can try as often as you want. You also may want to take breaks. If you're faster with U' 20, do that. Please use a regular speedcube, so for example no tiny cube that lets you do this fast but which is no good for speedsolving. Don't pick up or drop your cube, I just want to know the time for the moves.

Me: 3.28

The reason is that I just watched some Rowe and now I'm frustrated about my finger/turning speed. I'm starting to seriously practice this stuff now, and I'd like to get some goals so I'm interested in how fast for example this little exercise can be done. I know U20 isn't exactly what anyone would do in a solve, but I can't expect meaningful measurements of just one U so this is sort of an average.

My time was 4.06.

If you want an average:
Times: 4.71, (5.63), 4.11, (4.06), 4.94
Average: 4.59

I tried this with the left index finger and got 6.21 my first try. With the right index finger I got 4.31
 
U' instead of U is alright, whatever is faster for you.

Does cube size count?
Well, I'd say it's most meaningful to measure it with your normal speedcube as ultimately I am interested in solve times. So a tiny cube that lets you do this thing fast but which is no good for speedsolving otherwise is not good for this analysis.
 
2.90, 3.16, 2.90, 3.18, 3.35 = 3.03.
2.90's were pretty epic. I highly doubt anyone has subbed-2.5.

EDIT: 2.87. I can't go any faster than that, it makes my fingers hurt.
EDIT2: 2.81+2 >_>

Pretty easily 3.5-4 on my mini QJ 3x3 but on my type F I'm 4-4.5. I think it is a lot in how easy it is to do the flick on the cube or how easily the cube will turn as I do the same range of motion with my finger on either cube but my mini turns much more easily.
