I suspect you have some video setting(s) affecting the %
At the very least, using -refreshspeed for my machine makes my 100% for both turn into 96/97% on PONG and 90% on BREAKOUT

I get 100% on Pong (over 200% unthrottled), and I can get 100% on Breakout if using fskip6 (3.7GHz not quite enough).

$ lspci | grep VGA

-str is redundant in that case. -bench is 4 commands and will surely be faster than showing graphics and sound every frame.
-bench 90 = -str 90, -nothrottle -video none and -sound none. I can't figure out why -str is not showing correct seconds.

In any case, if you cannot show a solid 100% from "mame64 pong" without adjusting default settings - giving results for this particular issue won't help.

if a machine has a severely unbalanaced per-frame load then you can get >100% unthrottled despite the game not actually being able to run at full speed (as the average of 2 frames is still >100% even if a one frame in that isn't)

not sure that's the case here, but it's one possibility.

I'm tempted to close this issue unless more evidence can be presented that proves something is actually wrong here.
Any objections?
