This is a real problem.
Brett has never come clean about his sources, probably because they're so few that it's impossible for him to get consistent data. The proof is in the pudding: Brett has consistently missed trend changes, his margin of error is not within 10% as it's often tossed around here - it's around 10% averaging everything (which means big spikes happen) and only on the big ticket numbers.
Ultimately this means his numbers are not reliable.
GAF staff might not like Brett but since his numbers aren't good, there isn't room to argue.
Personally, I'll pray for leaks to force NPD's hand and save the day.
