Most pilots that are willing to take any premium trip will submit multiple smart pickup requests with varying criteria (days, Airport, etc) so they don’t miss out… so when the scheduler changes a 75 to 100% as soon as they hit enter it’s assigned to the smart pickup pilot who is most senior. If you wait for a notification to be sent to you by text then you are losing out. Senior pilots who wait for 100% to drop will sometimes get edged out by a more junior pilot who would accept at 75% who would have otherwise lost out.
