Chord diagrams are for beginners. If you are doing Travis Picking I think it is safe to say you are not a beginner.

As well as alternating thumb there is double alternating thumb. On an A chord the thumb picks;

5th string, 4th string, 6th string, fourth string.

Perhaps that is what you were mentioning in your last post. If so you are definitely not a beginner.
