The history of my ROH, with a line through the changes 1/2 (starting out), 3/8 (skating on crappy ice), 9/16 (my patch days), 5/8 (returning to skating--and I didn't care because I was going to sell the skates and use my Harlicks), 1/2 (back to where I started after I couldn't get the Harlicks to work out). This is how my tech tracks me, cause I'm all into experimentation and stuff.
There's also a string of numbers that I don't know what it means, and a piece of masking tape. Bottom of the skates is the tech's world. I don't ask, I don't touch.
