Interesting rubber chart - karahashitakkyu

[shinshiro]

Hi guys

While I was searching for informations about a rubber, I discovered this rubber chart below made by karahashitakkyu. The x axis represents spin, and y axis is speed.
I guess that their staff test the rubbers and put them on the chart, comparing with previous rubbers tested.
I found it very interesting.
What do you guys think about the chart? Do you agree overall with it? Or are there some major discrepances in your experience?
Of course this is just their opinion, can't say is right or wrong, but I'm curious to know what do you think.

I tried to translate a few rubbers names (sorry if it has some mistakes, I can't read japanese):

A few notes about this chart:
- each color represents a brand (black = butterfly, dark pink = tibhar, gray = stiga, purple = mizuno, and so on)
- the pins that have a red circle are chinese-like rubbers/ hybrid rubbers (look at Dignics 09C / DNA Dragon Grip)
- the fastest rubber is bryce high speed (forgot to translate that on the chart....)
- the spinniest rubber is nittaku hurricane pro 2 (also forgot to translat that...). But it seems this rubber is not comercially available anymore (at least is what TT11 site says), so the spinniest rubber available now is DNA Dragon Grip (note: they didn't put any DHS rubbers on the chart, probably because they didn't test them I guess)
- of the non tacky rubbers on this chart, there are only about five they think have similar spin capabilities to T05 (outside Butterfly). They are: Donic Bluestorm Pro, Cornilleau Target Pro XD 47.5 and 52.7, Mizuno Q4 and Q Quality

Interesting that Stiga DNA Dragon Grip is supposed to be the spinniest rubber of them all. Not many people seem to use it. I have a new sheet in my drawer. I will try it out soon.

Thanks for the chart. I'm currently trying out MX-D as a replacement for my T-05 I've been using. In terms of spin, I find them to be so close that the difference is smaller than what the chart would suggest imho. I think the y-axis speed is a pretty good approximation for my two rubbers. Durability remains to be seen, but so far so good after 4 weeks. TT11's 4=3 deal is a game changer for me.

How was the chart data gathered? What equipment did they use.
I like the idea but see no proof the data is valid.

Interesting they have the O7 as the fastest rubber. Wonder why I dont see more people using O7
