I have started a fairly simple analysis of the difference between my 4iiii Crank arm power meter and the power output from my Tacx Smart trainer. This is here: Power Measurement Comparison I found this interesting video about potential issues with strain gauged crank arm power meters:
In fact the author (presenter?) has made a number of other interesting videos about cycling technology - I first came across him via DC Rainmaker so I won't take all the credit
Quick Update 3 March 2019 I had not used my tool for a while and fired it up today only to find error messages everywhere and I could not add any data since ~19 Feb 2019. Some diagnostics showed that I had incorrectly used the wrong type of variable for the Activity ID, and clearly some time after 19 Feb this number became too large for the variable type I was using I have been through the code and I think addressed all the instances of this error, and tested it as OK. The latest release is here: V2.01
You will need to create a new database for this update to take effect - whilst I have made a lot of progress learning how to use a database, and I can create the database this program needs programmatically, I have not yet implemented changes to the live database.
The best way to create a new database is to open the application data folder (menu option). Close the application, and then in the folder rename stravaforms.ini to say stravaforms_org.ini. Then restart the application and you will be prompted to set the application up again including recreating a new database. Obviously you'll need to download all the data again as well I have been making slow progress to working out how to generate/acquire the StravaToken from within the application. There is still some way to go but I believe my application will live beyond ~August 2019 when it will lose the fixed Token
