The tower would probably be 13 days and 8 hours long (it looks set to start on Thursday and end on Wednesday, 2 weeks later, as has been the trend with most events). That's 320 * 60 = 19200 hp (minus your hp regen reset time, and your WG encounters). Let's assume you lose around 1k (taking an extreme amount here) hp. That's 18200 free hp.

You would probably have hp stocked up before the event begins, so let's add 415 hp. That's 18615 hp. You would probably level up 1-2 times, giving you another 930 hp. That's 19545 hp.

Per the tables above, you need 20830 hp to get to 200F. So 3-4 DN should cover your climb to 200F. This is assuming that you don't overflow (415 hp gives you 7 hours of away time, so that shouldn't be an issue.) These calculations are by no means accurate, but should be close enough to what you actually use up.
