Hey, I also started late because I lost my account, so I started around noon, November 29th. I am currently on the 114th floor, and am trying to make it to 200F w/o items (saving them). Here is how I calculated if I'll make it (could be errors, I've had a lot before):

Hours left in event (currently): 177 hours = 10,620 minutes

lvl-ups * max HP: (at least) 4 * 250 = 1,000 minutes

114F = (approx.) 188 hours min. to 200F = 11,280 minutes

So, based off these approximations (aren't terribly far off), I have 11,620 minutes available to use in the 11,280 minutes minimum required to reach 200F. So, if this is correct, I won't have to use any items to get to 200F, as I wanted to save them.

Now my 250 HP is a lot, it was 180, but since Friday I have mass reallocated to HP to take full advantage of the lvl-ups. It appears your lvl is higher, though, so that is a disadvantage. Anyway, that's just how I calculated it, hopefully w/o mistakes.

Now for celestial roses, I have 481 at 114F, but I have been very lucky (compared to crewmates and other users on wiki). However, even my crewmates have 500 CR around 130F-135F, so you should be safe to get Rokumeikan.
