m! a skill that "loans" a player 20* CR on recovered ships but causes the ship to get 0 CR per supply in repairs until the "loan" has been "repaid", so that the player can use a ship immediately after recovering it (or use CR-requiring campaign skills), then an elite tier that ?? gives you a free 20 CR bonus without interacting with the "loan" maths, putting you up to 40** free CR for recovered ships but you only have "repay" 20 of it before you start gaining CR again
* malfunctions, but no critical malfunctions, until peaktime is up then immediately eligible for critical malfunctions
** degraded performance, but no malfunctions, until peaktime is over then immediately eligible for malfunctions
also im sure theres a way to express the concept without using words like "loan" and "repay" but im not gonna workshop that
