I'm not able to fully understand the logic of how empty cells end up specifying chord durations, especially in odd time signatures. For example, in Take Five (5/4) section A, both Ebm and Bbm7 are followed by a single blank cell, but somehow the player translates this to Ebm playing for 3 beats and Bbm7 for 2. How does that work? What if I wanted to play Ebm for 2 beats and Bbm7 for 3?

An authoritative and comprehensive documentation of the beat scheduling logic would be great!
