I think they got in the single-digit thousands, perhaps 5-10,000, but I don’t really recall.
There must have been power estimates done internally, but if there was one ever made public explaining how much power they expected from enrichment, I didn’t hear about it. I won’t pretend I know the details of what they were thinking sufficient to do my own power analysis, but I didn’t think it was a terrible idea at the time; it was worth trying, and the results could always (I assumed) be meta-analyzed with later bigger results.
