Less tobiano in AC

[Nazarach]

I'm unsure where exactly to post this, so I hope here is fitting...

It has been a fairly long time since the To update and one might say the market is saturated enough - Is there a point when the tobiano marked horses in the AC will be set to a normal rate? Especially for the North African Barbs it is nearly impossible to find unmarked/non-carrier ones, which I definitely need/would rather use for my projects.
The NAB also can appear as unmarked in reality (as far as most searches and my lexicon informed me);

So please, when can we expect a lesser ratio of To carriers in the AC?

Support.
Idea of when the rate would be reset would be welcome.

I agree, tobiano really isn't that common in real life barbs...and also, less tobiano/lp in tarpans would also be great as IRL they are grullo only....
