Did you really need to tabulate your punts to know what you like?
Yes, it helped. I thought I had no luck with south americans, turns out I am not good with latinos.
Also I had not realised I got on with Chinese and Brits so well.
It makes it much easier to interpret the data in my opinion.
Most people would agree with your opinion in my opinion.
Provided the data is representative of your entire punting history you're good to make some bounded conclusions about the punts you've had assuming the SP community you're punting in isn't changing significantly wrt distribution of attitudes, behaviours, skills, perceived value of services, etc.
If your timeseries extends over a period where some/all factors change then generalisations may not reflect the current SP population profile and so lead you astray in terms of choices. If you start punting in a different part of the country/world then your sample may also not be a good predictor.
Switching to/from FS escorts to more expensive or cheaper ones or to/from massage parlours or brothels or "tantric" or visiting massage services would also impact your predictor.
Yes I was concerned about all your points but I went with what I had. This is not a predictor though it is an analysis with some of my conclusions.
Thinking about it, a pie chart may have been a better option. 
I am very much against pie charts.
Very good article here on why.
External Link/Members OnlyWhat we really need is a cream pie chart, though perhaps that belongs in the BB Avoidance thread.
Humour. We all need it.
I am surprised how high up the list Chinese girls are.
I get the impression from reviews on here that Thais are a much better option to tick your Asian box
I was too. Interesting that I have not gone to see any thais in my reports, but this is an analysis of my reviews not all reviews.
I think some of us need to get out more!!!
very much so
Can you start capturing stats like height, boob size, dress size, hips and waist measurements, Turkey teeth or not, BJ rating, so we can see if there's a correlation between BJ ability and natural or Turkey and BJ ability or height and BJ ability?
Some specialised interests there. No.
