You would want the 1-2 bends laid and rolled way before the season starts so it beds in properly. We had the same problem after the 0-11 season, we had everything re cambered we got the straights done and bends 1-2, then it absolutely threw it down for a fair while. 3-4 were done, but not as good as we would have wanted it. But as it happens it worked out not to badly in the end once the track eventually dried and the roadgrader was put round. Sadly, thats the Winter for you, its not easy.
