Wait, if 80% of your readers took the survey then why on earth are you doing any kind of fancy statistics to estimate that preference gap? If you’ve got a representative sample that covers a large majority of your readers, then you know what the gap is: it’s the gap observed in the sample, which IIRC was a little under 15%. Done.
(The factor-of-2 change in the meaning of that 25% figure seems really strange to me, too, but I take it the issue is just that the way it was introduced didn’t mean what I thought it did.)
