Actually you make a good point here when trying to "pre-empt something".

Without quantification you haven't got much at all. Afterall, no-body is saying that a springy pole is beneficial to performance. And absolutely no flexing is impossible in real life. So we are comparing different amounts of flexing and trying to assign different levels of performance loss to those. At some point the differences in loses is too small to matter. We can only find this point after quantifying "the info". And we need to gether these numbers (quantification) in an orderly, scientifically and most certainly reproducable manner (= evidence).

Otherwise we'll end up with the situation analogue to those 2 guys claiming they had achieved nuclear fusion in a glass of water at room temperature. Remember that story ?

There is a reason that mankind has developped so much new technologies over the last 4 centuries out of 30 millenia of existance and that reason is called the Scientific Method (= part of the entlightenment).
