I like to keep track of my tortoise's weight as a general indicator of health/growth and use a spreadsheet to track it and graph it. I know this is probably in the realm of OCD, but as a retired guy, I've got the time. It's comforting to see a nice steady rise. The tort in question is a Yellowfoot of undetermined gender, approximately 18 months old when acquired, and weighed each Friday, using grams instead of pounds for a little more specific number. The chart is below and covers the first 83 weeks of ownership.
