Here's a straight-forward comp for 3b and cf:
If you have a bulletproof player, you will see something like 6300 plate appearances while on defense. That translates to roughly 29 times that each roll will come up throughout a season.
A CF-2 and a 3B-2 each has three of those 216, thus 87 X-chances apiece.
For the CF, there are three hits (two singles and a double) on the X-chart - 15%. So, of those 87 X-chances, 13 of them will be hits--roughly 4.3 doubles and 8.7 singles.
For the 3B, there are just two singles on the X-chart -- 10%. So, 8.7 singles. However, four results are SI2 (single, runners advance 2 bases) with the infield in or the infielder is holding a runner. Plus five fewer DP chances. Of course, a 3B rarely holds a runner, so it's just infield-in scenarios. So, how many extra hits come from that? I can't imagine that many.
By the way, keep in mind that if your infielder is holding a runner, his range goes up, which is why I put more importance on 1-range at 2b and SS. Hey, I will play a 4 at first base, a lot of us will for the bat. However, that 4-range 1B is a 5-range 1B when holding a runner on base, which is 60% hit result on the X-chart.
