That looks like a normal spiky outdoor ride profile except MPA seems too low to have been pulled down that far especially if it was not “a particularly hard ride”.
Were you deliberately jumping or surging during those red spikes or just riding along?
MPA too low would explain frequent BTs.
What do others think?
