I've become quite familiar with repairing my fleet. This is due to internet disconnections and issues with my pc. I believe the current process can be very unfair to players like me, who for no fault of their own, are faced with numerous repairs.
I've noticed that even a small to moderate 'bump' will kill the avatar and damage the ship extensively, requiring up to 1000 exotic scrap units. to repair in a reasonable time I'd suggest that the level required for death and extensive damage be raised to, say, 80%. Further more, the deletion of scrap carried on the Avatar or in the Ship's containers, is quite harsh when the minor damage occurs, this includes deletion of any pure ingots or ores used to nanocraft scraps (also including deletion of other carried inventory).
I would also like to suggest the introduction of a level 2/super/epic/professional Repair Tool. One that can undertake repairs in one step instead of the current two, and, repair much quicker than the current tool. Such a tool could be purchased from the system or crafted, but with a heavy price to reflect it's superior qualities. Having this would reduce the 'grind' of repairing an extensively damaged large M or L ship, allowing the player to continue meeting their game goals for the session, rather than 'grinding' for 2 hours doing repairs - especially after an internet disconnection etc., which they had no control over.
