Justify the 255 Max Whisker Count

A "null" Whisker is two bytes long, e.g. 0x06 0x00. A CATS packet can be up to 8191 bytes long, which would suggest a maximum Whisker count of 8191/2 = 4095 Whiskers in a single packet. However, the Whisker section says that a CATS packet can only have up to 255 Whiskers.

This maximum Whisker count should either be removed, or justified.
