The ink is very helpful as it will tell you that your getting too close to the edges.
You only need a few licks at the very end with full width/length abrasive, don't go too far as you will ruin all of your work.
Don't follow any video instructions that won't demonstrate the test at the end with feelers.
You won't find a video of lapping done correctly as far as I know, but maybe someday someone will do one.
