Assuming that you blow the whistle and look at the clock, you put back on the clock what you see. 5.10.1b comment says that the official signalling and looking at the clock is considered the same as lag time. So if you look and see time after you blow it dead, you put it all back on there. In the case of 1.9 if the official blew his whistle then looked at the clock, and the clock operator let it go to 1.2, I say put all 1.9 back on it. IMHO..
