Back in dec/jan we had discussions where people were of the opinion that 9 different PS values is too much, 3-5 would be enough. That got me intrigued then to plot the distributions.
Now with more waves released/resp. spoiled I updated the material. It contains up to wave 10. We know all PS values, but number of EPT carriers for latest wave probably is an underestimation. Caveat: as this is pure fun work, it might contain small errors.
You see the pilot values 0-12 at X axis, Y-axis shows number of pilots in each column. 0 is included as we have Torkil so every faction potentially having a 0 skill pilot, likewise can Roark make rebels 12, and Empire has Epsilon Ace. Adaptability and Veteran Instincts can shift all EPT carriers 1 step down or 1-2 steps up. 
Upper right is all pilots. A very nicely shaped bell curve (a small dip at 4, this is S&V, see below), so mid-level is the most frequent.
If we look factionwise (observe that axis is 18 for all of them), then rebel is most equal, very similar frequencies at 3-8. (Back in the days they had a lot of 2/4/6/8, but now its more even.)
Empire has a more skewed distributions, a peak of 6, and slightly more 3&4 than rebels.
Scum and Villainy kept it overall lower levels (experienced pilots mostly 5-7, 8 almost absent), and it distinct dislike of the value 4.
Overall faction comparison is the lower right (corrected for uneven number of pilots in the factions, observe axis thus scales to fractions of 1)
Lets have a look at EPT carriers. Adaptability and Veteran Instincts can shift all EPT carriers 1 step down or 1-2 steps up. not reflected in the graphes.

Again, all clumped together upper right. Still more or less a bell curve, but shifted higher up, and right flank cut off (as more than 9 naturally not possible).
If we look factionwise (observe that axis is 11 for all of them), we see rebels having a more spread out distribution, while Empire has no EPTs lower than 4, and most of their experienced pilots are higher up, at 6-8). S&V has many 5 and 7.
Overall faction comparison is the lower right (corrected for uneven number of pilots in the factions, observe axis thus scales to fractions of 1)
Last out a faction split, I wanted to see what happens if you exclude Resistance and First Order, leaving only OT stuff.
