Speaking for myself one could also re-define your "subjective opinion" and "speculation" into "feeling". The "feeling" you have: "is this version I am having now better than the previous one?". You (we) do not have proof of that so our opinion is "subjective" and full of "speculation" but that doesn't mean our "feelings" are not right. And based on our "feelings" we eventually do produce better versions. Observations are leading to new ideas and solutions that are full of speculation and expectations. Later based on your experiences with the new software this leads either to the rejection of the idea or to a deep rooted conviction the idea is good. In that stage you still have no proof. Still you claim: "this version is better" based on your conviction. And isn't it true that in the end you mostly are right? Unfortunately not always, but definitely mostly. It's the same asking a GM: "why this knight on e5?". Answer: "Because it belongs there". Subjective answer, full of speculation, no proof but still the GM is right. Feelings... Aren't the feelings we have on our software not the driving force behind the improvements we all made through the years? Looking back myself I think the answer is a clear yes. You can not proof chess, you must feel it :) - Ed - >- Don
