@Nathan makes a fair point, though with best tips I'd add that how it played out was stronger at the weekend.
The fix that worked on best tips was simple enough — give it a full week before judging it.
For me the part I got wrong at first with best tips is whether the questionnaires are worth the time.
For me the point where it either works or doesn't with best tips is what people say versus what they do.
The part I keep getting stuck on with best tips is whether the questionnaires are worth the time.
Short version for anyone testing best tips:
- Do not take silence personally; with best tips it costs you a full weekend
- Give best tips the first month before deciding — how the volume moved was behind on everything except volume
- Say what you are looking for in plain words — on best tips that mattered more than anything else
