I thought it was pretty ridiculous when Envoy put out the latest version of optimized boarding. It is hard enough to make the extended turn times at a hub, let alone the shorter ones at an out station. Rather than building in more time in the schedule which would allow a catch up if a previous flight was late, it now makes all subsequent flights late.

BUT, since Mesa couldn’t make its times, AAG gave them more block time. See article and quote from it below.

American also will schedule more block time for many Mesa flights, a move that should allow Mesa to pad on-time performance. Flights that had been slated as late could now arrive on-time, according to DOT guidelines.

But Envoy would rather just take away performance bonuses from employees. Another example of tripping over dollars to save dimes and hurting themselves rather than helping themselves since they would have to reward the employees.
