I just released version 1.40 of R10Analytics. Main improvements are: multiple profiles, correlation matrix, spin computation method, PEI, backups, improved and faster import, more range target options, and a lot more. You can download it from the R10 Analytics website.
For those who don't know, R10Analytics is a free windows program to analyse all your shot data from the Garmin R10 in many different ways. You can download it and find more information on [Link Deleted]
