Yes Alex, the Zwiftpower timer starts counting as soon the event starts, whereas the Zwift timer only starts when you cross the start line. So for these big events you can be pedalling for a good 40 seconds in the pens before reaching the start line. The later you join the pen and the bigger the number of other riders the further back you find yourself in the pen. It’s a bit of a pain and confusing but it seemed Zwiftpower was the most consistent place for getting the times for our league.I find ZP times are consistently higher than Zwift times on these events (mine are below)
1 Z 01:13:22 ZP 01:14:18
2 Z 01:45:52 ZP 01:46:53
3 Z 00:57:42 ZP 00:58:21
4 Z 00:46:09 ZP 00:46:50
