The things about stats for me are quite clear. From the moment we use simple mathematics to understand and interpret the results given, we need to stick to this method. If we take the numbers, that do not make sense and afterwards we are trying arbitrary to create a mathematical logic behind, it's just a wrong way...
From the stats, we some references, for instance total numbers of putts. A simple mathematical logic dictates that if we add all our putts, we should end up with the total number of putts. Is this happening? No, definitely no.
Same logic with percentages. If the total amount of putts represent 100% of putting, the addition of the various percentages should be giving us 100%. Is this happening? No, definitely no.
On the other hand, the percentages on first, second, third, hundredth putt are spot on. If we add these percentages, we get a nice 100%.
In few words after reading nivlac's post, we can't be taking some arbitrary numbers, sum them up and trying to make a mathematical reason behind them in order to justify the final outcome which makes no sense. The numbers are there. If they don't correspond to mathematical formulas to prove them right, are definitely wrong....simple as that.
PS
Apart the percentages in putting, you can take a look as well if the numbers of the putts correspond or at least make some sense, with the total albatrosses, eagles, birdies, pars, bogeys, double bogeys, and so on...(for the sake of hypothesis, consider that all of them were made as putts...i know it's wrong but for the sake of it, just do it and see what it comes up...:)
