This will result in more flying for reserve pilots. The schedulers are often not good at their jobs, anyone that pays attention should be able see that. This is an automated way of eliminating waste because the schedulers often aren't savvy enough to notice it and eliminate it themselves.

End result will be an overall increase in reserve pilot productivity. You'd be foolish to believe the company would willingly do this otherwise even if you didn't have experience with reserve. If you have reserve experience and still don't see what they're doing here then you're either not paying attention or not very smart.

Chess vs checkers. Expect an overall increase in short calls and just as significant expect an average earlier start time. Less greenslips and higher reserve usage. I'm surprised it took them this long.

The only positive I can see is a commuter gets a bonus hour, but that will be negated often with uncertainty about the next days short call and the higher likelihood of an earlier trip the next day.
