I have rarely downloaded my Combo because I found the method tedious, long winded and difficult, plus the information gained was pretty useless. Pity, because some software I have used in the past, particularly that provided by Abbott has been so amazingly informative. I am thinking of the Insulinx meter I used before going on the pump and the Libre sensor. So I keep a spreadsheet. Don’t use it on a daily basis, but I do record significant changes And you can use it for occasional TBRs if necessary.
Ps if you ring Roche they will send you a disc with the software for downloading the pump
