I ran a half marathon yesterday using PacePro and a mapped course and PacePro segments set to every mile.
On each segment change the Audio prompt gave the summary of the upcoming segment and also reported me as being X seconds behind. This contradicted the watch display of X seconds ahead (X was the same). Towards the end when the tiredness kicked in and the hills started winning, this flipped so the watch said behind and the audio said ahead - either way there was a contradiction.
Is the audio getting confused with the +/- symbol before the time?
I am on v8.37, I last used PacePro on v8.16 (1st May) and did not notice this was an issue but that's not saying it just was missed.
