I'd go back to 2.75U next shot, as Serryn suggested. On this forum, if you are following TR, we suggest that for anything below 150, you test, DO NOT FEED, and post for help the first time you get that low a number. There are usually several options and people can walk you through them - provided of course someone is around. One of the options is a temporary lower dose. Anything above 150 is OK to shoot. You might want to review the Sticky on Shooting and Handling Low Numbers for the options for next time. Most often when you shoot a lower number, the entire cycle is a lot flatter.
