I personally find the numbers misleading.
I just got both the other day they are both drilled 3.75 x 4.75 (Pin x MB).
The Robo is much stronger in the oil than the Machine.
I haven't got to use them on the fresh yet but I gave them a trial run yesterday on a shot that was left over from our Friday morning Seniors league. The lanes were fresh inside but the track area was sloppy from all 8 player playing that area. All were using weaker balls or plastic pretty much pointing it at the pocket definately no crankers burning up the shot.
With the Machine I had my best look standing on 35 setting down on 25-26 and targeting a break point around 6-8 at 45-48' I was able to get it to push through the track area to the outside where there were clean backends. This gave me a strong transition off the dry not a flip but definately strong. On the other hand I could not get the Robo to push through the track area playing the same line/speed, when I raised my speed a bit to get it through it would not recover due to using up too much energy. The best line for me with the Robo was to standing on 30 setting down on 20-21 and targeting a break point around 10-12 this allowed me to go where the carrydown was heaviest which gave the ball a touch more push for a smooth transition to the pocket. When I played that line with the Machine it would kind of squirt in the carrydown it would still get to the pocket but was a bit inconsistent.
The condition is 70ish units from 8-8 @ 10' tappering down from there so there is no lack of oil in the middle.
The OOB of the Machine is a very light polish.
See profile for more details.
Hope this helps.
