They need to reshuffle it IMO.
Raw should be on at 8:30pm on Tuesday (like Fox Sports) 2x replays one being Friday 5:30pm and the other being 12pm Saturday.
Smackdown should be on Friday nights at 8:30pm (Thursday if possible as they are taped). With one replay on Sunday 12pm.
Heat and Velocity can be after the replays of both programs. So Heat will be on after Raw while Velocity will be after Smackdown.
Experience...well just pick a day really.
IMO, I would rather see Fox Sports own the rights of the WWE, we would be able to get more replays as I think Fox Sports would replay Raw 3 times in one week which I often found useful back then.
