If I can see a youtuber made a combo video full of teleport into F2 link, the window for teleport into B1 link is definitely bigger.Its roughly around 1 or 2 man. Probably 1. Its slightly tighter than Laos DB1xx4,4 which is 2f.
(or it may depend on something else. I notice linking F4 ~ teleport, B1 is much harder than B3 ~ teleport, B1)
