"She adds that the goal for Starship this year is to reach orbit, deploy satellites and recover both stages. And of course to launch Falcon 9 148 times."

1. Reach orbit (As they have done most of a suborbital path, anything suborbital does not count, it must circle Earth at least once in a single flight.)

2. Deploy satellites (These have to circle Earth at least once, deploying from suborbital so they don't circle Earth won't count.)

3. Recover Booster (This can be via a catch with a launch tower, landing on legs either on land or on a barge and then brought back to land or soft water landing and then towing or other means of transport back to land. Being able to carefully inspect is what is aimed for here, so exploding within 2 hours of landing/catch is not sufficient, towing to a different location and then sinking it is not sufficient. Taking some parts for inspection and sinking rest does not meet my expectation for 'recover'. If they sell/transfer it to a scrap merchant who takes it back to land this is also insufficient.)

4. Recover second stage (same requirements as for booster)  

The 25% increases are once only for each of these goals. Doing one of them 4 times and none of rest resolves at 25%.
