Be careful applying a blanket figure during operations. There are many variables which you should consider, such as;
Runway width
Taxiway width
Runway/ taxiway corner fillets, or not
Contamination present on runway/ taxiway
Length of taxiway and potential taxiway over-run area
Aircraft serviceability
Wind, especially crosswind
Rate of decelleration
Autobrake stopping distance
Experience level of both crew
Traffic situation on taxiway and on approach behind you
There are more, but you get the gist? Account for all the variables and have a PLAN, based on these variables, but remain flexible enough to modify that plan if something changes/ isn't working. Be careful turning off at high speed....
