?In Your table the Higgs frequency 1180. The Fanatic frequency 1491. But the manufacturer says that the Higgs faster blade than a Fanatic ...And You get the opposite ?

Oh, I see: what is auto-translated into "Fanatic" is actually the "Zealot" blade!

Yes, this is what I get: Higgs has a much lower frequency than Zealot.

My playing impressions confirm this: I played with Higgs several months ago and with Zealot recently. I can confirm that Zealot is a rather fast and rigid blade, while I did not like Higgs and found it rather slow (I put slow rubbers on Higgs expecting it to be fast, so my comparison may not be 100% accurate).

It could be that my Higgs is a lemon (bad sample, or broken), or that the manufacturer data not accurate.

?I use the Fanatic + Tenerjee 05 + Karis M + (2.2). And Higgs + Karis M + (2.0) + Nittaku Fastak G1 for 6 months, ... It seems to me that Higgs is faster, more powerful (but I'm not a pro, but an advanced amateur ...). In your case, I doubt that Nexi can make a substandard product ... although ...
        And also: Higgs has 7 layers of wood, and the Fanatic has 5. It says something about something.

Indeed, Higgs is 7-ply and advertised as fast, so I was puzzled about my Higgs being rather slow. But the frequency I measured seems to confirm this. Maybe my blade got damaged. It would be interesting if you could measure the frequencies of your blades, so we can compare.
BTW, I'm not a Pro either, and probably not even an "advanced" amateur.

Was out sick for a while. Finally fully updated the list with arg0s latest data set. Thanks a lot for that, it's a lot of good data.

I'm pretty excited to see the amount of blades in this 'database' by now. Good work everyone who contributed!

i have a clipper and a eb7.some rubbers make the eb7 slower than clipper while eb7 is off+ and clipper is off.do you know why?

All super thick balsa core blades will pitch over 2k. I bet the Joola Kool would for example..

this sounds very interesting.
if you send all the blades to me i'll do FRF analysis with LDV or at least accelerometers. ;-)

I just saw this thread and the spreadsheet! Amazing work everybody! I am amazed to see such comparison between blades of different brands and I guess the frequency-speed blade correlation will at least give an order of magnitude for players and professional EJs to compare blades. 

After seeing the data I can concur the subjective perception of speed of the following blades which I have owned in the past or that I currently use matches proportionally with their obtained frequency results :

- Schlager Carbon
- Primorac Carbon
- M. Maze
- OC CR
- Clipper Classic
- Clipper CR
- Energy wood
- Butterfly Korbel

I have been a member of this forum for a long time and I think this is one of the most useful topics ever created here.

Blades by Charlie  Flashdrive: 1402 hz (88g)
Sanwei Fextra: 1325 hz (82g)

Reference blade (everything else was measured in the same way, so this should help compare my results to those of others), Donic Ovtcharov True Carbon: 1536hz (82g)

Just a suggestion, I know you have the legend near the top but perhaps include the manufacturer's claimed play characteristic (from DEF to OFF+) and the conclusive test results (elucidated from freq. testing) beside the blade? I think this might make it easier to compare rather than scrolling up and down

Edit: and you may also want to test your hypothesis sooner or later (I think the amount of data is enough) by running some statistics to prove it either right or wrong. Simplistically, you can do a students t-test. Just some suggestions though Smile

The issue is that different manufacturers use different categories, some from DEF- to OFF++, some a small selection. If I remember well, Nittaku almost exclusively uses DEF and OFF (Violin is OFF; there's a handful of relatively unknown Nittaku ALL blades).

I'm a bit rusty on statistics, but why would you use a Student's t? that's the most wrongly used statistical test in medical literature... It's for comparing two groups having a normal distribution. Here we have two variables measuring the same property (speed), one of them being ordinal (ordered categories). You need a non-parametric correlation analysis, such as Spearman or Kendall rank correlation.
To be correct, you would need to perform this analysis "per manufacturer", or normalise the categories and factor in that some Manufacturers may be more accurate than others.

I did some correlation analysis with other measures of blade speed, such as those disclosed by Nexy or TTGearLab and there definitely is correlation (p<<0.05). See this post.

Yes I understand that each manufacturer use different categories but the goal of this spreadsheet is to normalize the categories by the given frequencies, no? Nonetheless, I think it would be helpful to see what the manufacturers’ measured/claimed and compare it to what we observed and measured (from the frequencies).

You are right, historically the t-test was inappropriately used in medical literature, however, we aren’t doing anything medical here are we? I only suggested the t-test due to its simplicity and the fact it can be quickly done in Microsft Excel. Additionally, I thought the focus here was to group/categorize blades with the given frequencies, based on the hypothetical claim/rationale. Nonethless, the t-test is still robust and widely used in the scientific community (it is also first hand used to quickly check if there are any significance at all).

However, I do agree with you, if we get down to it (scientifically) with the variables given a 2 or 3 way ANOVA (depends on what you want to compare) should be conducted in conjunction with a statistical correlational analysis. You are also right with the fact that the comparisons should be done as per manufacturer or if comparison among all the blades then a ‘housekeeping’ (most accurate and precise) manufacturer should be selected for the normalization. The question is, which company should be selected and would we be introducing bias? I’m not sure if there are any statisticians here but in order to do these analyses we also need reputable licensed programs/softwares and the problem with this is they’re generally not available to the community (require hundreds of dollars, or subscriptions) - that is, unless you painstakingly and tediously conduct all the math, but how precise and accurate would one be compared to a licensed program? This gets rather complicated and I doubt its required since were not publishing any report on Nature or any other scientific journals.
