I would say its quite common for a PCP. At a competition last week when it was between 4 and 8 degrees Celsius, most people were going through the chrono at between 15 and 30 FPS less than it was when it was warmer. Nothing to worry about, but you may have to adjust your settings/ clicks for hot and cold weather like we do here. Neil.
