The wiki listed the amount of frames it takes to cancel each stance entrance into guard, but I amended the values to have the stance entrance frames listed in the wiki as is standard. Just to keep records, when the moves are cancelled into block they are:
6A+B BE: -38
LI B: -66
LI (B): -35
66B: -50
RC AB BE: -36
RO B: -25

The frames on 22B/22(B)/11A might also need to be looked over, but I'm not sure.
