User blog comment:SolarMist/Ancient Japan's Got Talent!: Floor Progress Chart/@comment-201.153.119.150-20131129043334

actually im doing the math calc myself and im about to reach the same conclusion (im still considering the floor 151 before the first part rankings.

I think Zynga doesnt want the majority of "free" players to reach floor 200 without squeezing at least a few "free" given candies and such. so basically most of the "squeeze-time and no sleep" method will ultimately make the regular casual player aim for floor 150 (remember ninja village event?)

Free Players that stacked up on the candy freebies should be able to reach floor 200 without much of a problem, and as a free player myself, i found myself using 10 stocked up candies (500 hp) without any hp overflow from recovery and im currently at a healthy lvl 70 floor as of day one, which gives me reasonable timeframe (not by much) to reach lvl 200 safely without sacrifiing too much sleep, and just in case, i got another 20 stocked up candies (god i hoard these things!) should i ever require to reach a goal or in case that i overleep (im going zombie mode as well) advancing every 3.5 hours (210 hp) toreach my goal of getting to 200, a chance for 1st part rankings (most unlikely) and ultimately try to attain kinnara.

Best of luck!
