pianoloverus I'm pretty sure Nightowl was clarifying something you misunderstood. When WieWaldi said "I doubt, anyone can do 40 pieces this hard, at this perfection", he meant everyone participating in this challenge. I could be wrong, but to me his intent was clear. You're adamantly arguing a point no one will disagree with.
As to your second point, this is very reminiscent of the Molly Gerbrian thread where you started arguing about the efficacy of Molly's methods, thereby hijacking the discussion created for people who were actually trying her methods. You had not been trying her methods, but decided to use the opportunity to tell everyone there her methods were questionable. Similarly, without even participating in this 40 a year challenge, you have entered a discussion for people attempting the challenge and are telling them they are wrong. If you want to discuss the efficacy of the 40 a year challenge, I suggest you start a new discussion, and anyone who would like to argue with or against you can follow you there.
EDIT: Apologies--you weren't in the original bunch who started arguing about Molly Gerbrian. But the point still stands--if you want to argue about the usefulness of 40/year, it's best to start a new discussion for it.
