What is this you have posted? An email to ecogra or a conversation with Unibet?
Honestly, it sounds a bit like you have confused things by trying to make a case that they do this all the time on purpose. Has this happened to you or anyone else you know of another time?
SBR will try to help you but without any documentary evidence of the
correct regular time percentages it might be a tough argument to mount this long after the event and their rule change.
