At ehe Moment I experience miscalculations with the ELo calculation in the tactical problems sections. It soes some strange calculations, like I solved the problem, due to a slow connection to the server it took a while to update the right panel, where it says i.e. (+6) but I've only got one point added. Sometimes I even get points removed despite having solved the problem correctly.
Example: I was on 1522, solved a problem and got after that 1524 (+7)
Because you'll get substracted 5 points if you refresh the site I guess it could have something to do with those penalty points. Maybe the program interpretes it as refreshing if it tries to repeatetly connect to the site?
Does anyone have the same issue?
