Is it normal to feel worse before better? Nobody told me that.

Three questions kill most of the confidence in a thread like this: sample size, blinding, who paid.

The last ten percent of a taper takes as long as the first ninety. Nobody says so until you are in it. Same for me with a history book, unfortunately.

If it came with a repeat slip, the slip beats every database.

What is the first thing you would read if you were starting from zero?

Split orders. Two small parcels beat one large one for reasons that have nothing to do with price. Two months in on a tracking gap and it lines up.

I would take the narrow conclusion. Broad ones are more interesting and less true.
