I know i sound like an idiot with the questions
But you mean wait until 15 non hit then bet the non hits with +1 -1
We want 21 uniqies then go in?

Repeat after me "I am not an idiot...I am not an idiot...I am not an idiot..." OK now we can continue.
To answer your question:
You do not need 21 uniques.
Just take the last 10 numbers and work with them as explained in all these pages.
No fancy progressions just +1/-1.
Do not try to reinvent KTF it works fine as presented.
Learn to read the trot.
I think that you are involved in so many different systems you are just confusing yourself.
If you want to play around with different systems that is fine but KTF takes a lot of time, effort and studying to master.
If you want to play to make money then concentrate on KTF until you understand it.
As I said before, KTF has a steep learning curve but it does work IF you take the time to read the information available in this thread, the Jackpot Joy thread and anything to do with Winkels GUT procedure(s), especially on the VLS forum.
I hope this helps.
