I've looked at the top 100 again this morning: there are no SLP books listed but all six of the new releases are in the 'hot 100' of new and forthcoming publications.
I think it will be very hard to draw any meaningful conclusions from these listings: I've checked them frequently since May of 2016 and have been unable to read any entrails from them. In January of this year, all five of my House of Stuart books suddenly shot into the top 100 and remained there for a whole weekend but subsequent sales figures from Tom revealed no significant increase in sales for that period. I'd be very interested in any conclusions you come to.
