## C2/5269 data: chance of Umaro's attacks

(NOTE: Carry is always set when accessing the data at C2/5269 through C2/527C, so effective values are all 1 greater than those listed below [with FFh wrapping to 00h]. This is quite deliberate, as the sum of the values must fit in a single byte.)

## C2/5279 data: chance of type of encounter

(Each effective value is the Numerator of probability of getting a certain type of attack formation, in the order: Side, Pincer, Back, Normal/Front) (Denominator of the probability is the sum of the effective values, excluding those of formations that were skipped at C2/5250 due to not being allowed.)
