I need 50 runs to collect enough photos to get both breen ships (20hrs x 50 runs = 1000 hours)
heh, there is a problem with your logic. Yes, you can only do a run every 20 hours but you dont have to play the game for the time you cant do a run. All your 1000 hour calculation does, is give you the minimum amount of elapsed time to get the ship once the event goes live. And honestly that isnt even correct. As some will use lobi to get more photos and some will have photos saved from last year.
