Shipyard shuffles, continued
A couple of things about this case. Since the yard is size 100 (not pictured in the screenshots) and only working on one other ship, the advantages of doing this are not immediately apparently in the repair estimates for BC Repulse herself. However, the advantages for total repairs are shown here, since White Plains remains in the shipyard the whole time.
When I load the July 31 turn, Repulse is at 99% repair points at pier side. This would result in 1 point of Sys being repaired, but I put her in the shipyard. Voila - a point of engine damage is repaired (since engine damage is at 2* float). On August 1, she's at 36% so she goes back to the pier. Since the port isn't working on much, she actually repairs almost a full point of damage and is at 13% the next day, so she stays at the pier. But then on August 3, she's up to 88% - high enough to get repaired in the shipyard no matter how much it's working on, and the major float goes down to 5 the next day.
Since the shipyard isn't working on much besides Repulse, the Shipyard-only repair estimates over time for Repulse are not actually decreasing faster than the days are passing, but look at what happens to the estimate for White Plains: it jumps up when Repulse is in the yard. Also, in about 18 more days at the most, Repulse will be down to the magical 5/5 float/engine damage threshold and be able to repair completely at the pier, so if the difference between pier and shipyard is still 30-something days, that's a savings of about 2 weeks.
This will actually become more difficult shortly, as some of the shuffled repairs will be "wasted" on repairing a point of major float instead of engine due to repair bands. Basically, I will need to do this 8 or 9 more times, not 6 as stated in the screenshot, because I will need to repair major float down to 3 (or perhaps even 2) in order to get the engine repaired down to 5.
This works best at large ports with a moderate to large amount of naval support, and it doesn't really matter the size of the shipyard. My instinct says the smaller the better (so long as it can fit the ship) because otherwise you risk the shipyard adding on too many repair points - taking you from 97% to 40%, for example, and then you put her on the pier and she stays there for more than a couple of days at numbers like 32%, 25%, 17%, 10%, 3%, then finally a 90-something... Instead of the ideal, which is 90-something percent at pier, put it in the shipyard and get a point knocked off and around 30-40% repair points, put it back to the pier and get up to 85-99% repair points, and so on. Apologies for the tall screenshot.
