Good drill.....I do something similar to warm up, something like a ladder drill......I also always rack all 9, I need the break practice...
Full 9 rack, break, removed all but the last 3....as soon as I run out, break full rack and remove all but last 4.....and then all but last 5.....and so on.....I always try to leave the highest balls on the table and run out sinking the 9.....repeat until the full rack is run.....
Unfortunately, at 3 ahead, I'd probably just spend all day at the 5, so I just move forward after I run one rack.....it serves as a great warm-up to hit a few different shots and get in stroke....then work on whatever practice shots I want to concentrate on.....then mix in that 8-ball drill that was posted the other day, and then some 14.1......
