Honor needed to reach each Rank?

A few people have tried to break it down including a poster here Dragonballz who posted this:

For the nerds, I extrapolated a curve and y = -9407.051 + 11082.26x - 1943.109x^2 + 267.8953*x^3 seems to fit where Y is the Honor required to hit a rank threshold, and X is the Rank.

Rank	Honor	CP	Change Factor
1	-0.004699999999	0	1
2	7128.1954	2000	1
3	13584.9211	5000	1
4	20977.5442	10000	0.8
5	30913.4365	15000	0.8
6	44999.9698	20000	0.8
7	64844.5159	25000	0.7
8	92054.4466	30000	0.7
9	128237.1337	35000	0.6
10	174999.949	40000	0.5
11	233950.2643	45000	0.5
12	306695.4514	50000	0.4
13	394842.8821	55000	0.4
14	499999.9282	60000	0.34

Plugging in for a Fastest Run to max would be

	CP	Rank	Honor Required
Week 1	9000	3	21000
Week 2	24500	6	64844
Week 3	37000	9	175000
Week 4	49500	11	394842
Week 5	55200	13	500000
Week 6	56900	13	500000
Week 7	58600	13	500000
Week 8	60300	14	500000

This matches the 8 Week to rank 14 they stated in the original post, so I am going to assume I am at least close.

The only thing is that Blizzard says a max of 4 ranks and that chart shows 3. So I’m not sure but I actually hate getting into spreadsheet math etc so
