Can someone take a moment and explain about the "training details" section on the players page? I understand the legend at the bottom - mostly - but what do the lengths of the bars mean?

Thanks!

Ah. Thanks.

So just to make sure I have this right, the bars on the far left that are dark red mean that the player has had very little if any training since the last increase in that skill? I mis-interpreted this to mean they were no longer capable of increasing that particular skill, so I shouldn't train that skill anymore.
