The chart is very flexible. the assumption is 15 length string equals to 4
sets of draws. So reducing a string by 2 sets cut your time frame with few picks
so lets see your workout:

6*6*6*6(1296 picks)= 81 picks with repeats removed.
I think 10000 picks to 81 is good .
Lets break down the 81 picks for waging strategy
A lead digit like 0 is 27 picks
A front pair is 9 picks
A front Triad is 3 picks
Playing 10 or less picks for split bet this way is a good deal.
I want you to select your own base line, what you did is right.
