In any discussion of statistics, by definition, 50% will be above teh mean, 50% will be below the mean.

Guys come on!

By definition, 50% will be above the median. The mean is something else

Take 10 numbers
1,2,1,2,3,2,1,2,5,400

Mean is over 40

9 of the numbers are below the mean

90% of the numbers are below the mean

OK, you are right. I didn't put much thought into it. It's just a common thing you see on the net, esp where human intelligence is involved.

Eg Why are Americans so stupid ? Because 50% have below average intelligence.

Kinda thing.

I always did hate statistics as a subject. Blew chunks at Uni, fo sho !!

This is a great thread, I think I might be shocked into recording sessions to get some more relevant gear, I like yours Sausage, very s****y

Just download your csv file from GPSTC and save as an excel (*.xls) file for easier formatting. Add some extra columns with your board, sail and fin details per session (10minute exercise) and some colour if you want. I wrote a sum to add the number of times each piece of equipment has been used.

PS - Mine's not that sh1tty is it

Please excuse Sausage. We're not all wind geeks up here, its just there's been no wind in CQ for weeks now and if he ever stops talking windurfing............well..............I think he'll just explode

^Ian, I reckon I'll explode if I don't go for a sail some time soon.

My 2009 stats show that my big gear was by far the most used. (some more pretty pictures for Haggar

)

Here are my stats from 1/1/09 -31/12/09

Isonic 94 - 39 x
I122/Jp122 - 17 x
Jp49 - 6 x

6.2 -19 x
7.0 -25 x
8.6 -17 x

You really cant do without a 6 & 7m with a 90L board. However this year the stats are leaning more towrads the big gear, due to much lighter winds, well so far anyway.

But in your example 30% are above the median and 30% are below.

Back to the ~~boring~~ interesting statistics, donuts without icing.

I borrowed the JP from Mineral for the LOC, and I only got the CA recently.

The 6.2 came out of retirement for one day and then went back !

About 80Kg and sailed mostly around Perth with two weeks in Lancelin at Christmas (got PB's in Lancelin Bay using the Koncept 5.8 and Sonic).

I was a bit surprised I used the 4.2 that many times. Getting the speedsailing bug means I used the 5.8 Koncept where I probably would have been bump n jumping with a 5m ezzy in previous years.

I only got the 6.5 (and borrowed one a few times) this year, never uses such a big sail before. Certainly increases the days you can get on the water.

From this thread we come to the conclusion that there is bugger all wind around at the moment.

green line indicates average wind aver the last 60 years

red line indicates average wind over the last 30 years.

mackay has more reliable wind than Lancelin

and green trumps the lot.

As a relative newbie, I really like what the stats are demonstrating. It'll help heaps in decision making with new gear - i.e bigger gear gives more flexibility and t.o.w. Unless I've got it wrong though, a critical issue is the weight of the sailor, so any chance when you put your stats up you could include your weight.

Thanks
