Sorry to hear about the hometown flooding. I hope its not too bad.
As for the race last night, the big thing to try and do (others, please correct me if Im wrong) when being lapped and "shown the blue flag" is to not stop on the track or slow up too much especially on the racing line. There was a time that as I came up on you approaching the right-hander before the dunlop bridge you had stopped/slowed considerably right on the line going into the corner and I was not sure what your intentions were for a split second and actually got a little squirly coming out of the corner.
For example, if the leaders are approaching you on a straight, pick your line early (preferably off the racing line) and ease off the throttle until they pass. That said, if they are right on your tail on corner exit, hold your line, the leaders will get around you. For me, if I see a lapped car and im going to catch them right at corner exit, Im planning on being the one to move around the lapped car as I dont know if they see me or not so its my responsibility to make the pass and Im counting on them to hold their line at their race pace. That said, once the leaders make the move and are getting around you, be sure to make it clear that you intend to concede the position early before the next corner. If you come to a stop, then once they past, you will lose a bunch of time trying to let everyone through.
If you are in the mix of a series of corners slow down enough to hold wider line through the corner and allow them to pass to the inside but not so much that you are too slow approaching the corner.
The guys passing you will get around you. The key is make your intentions known early and having track awareness.
Again, I could be wrong but this is what I have seen and tried to do when in your situation such as last not.
Hope to see you next week. Its all about track time
