It works well for res pilots that live in domicile to bump up credit with turns. That’s the intent. For res commuters aggressive bidding 2 or 3 Day trips that start on a res duty period and go into a day off works well as long as it’s finish early on a day off. That leg plus any rig is over guarantee. Same going into a block of res duty periods. Kill an rdp if your getting used anyhow and bump credit substantially. From a lineholders prospective it is a bit of a give. There’s more pilots competing for the same flying in open time. I’m a line holder but don’t mind it as you never know when you could end up on reserve. More options is usually better.
