tracking error spreadsheet
After a bit of searching, I didn't find a tracking error spreadsheet. I did one in xcel. I can email it to anyone interested (xls isn't a valid file type for attaching, dang viruses) who would like to check it out (let me know if there are any errors). Or if you know of one, post a reply (I could check mine, see what else might be of use).
You adjust effective arm length, pivot distance and stylus angle and get the tracking angle error over 10 points across the record.
