10m - less good today?

Yesterday 4X1RF had spotted me 14 times by this time whereas today he spotted me just once.It may be that he is concentrating on 6m instead or an indication of less good 10m propagation on 10m?  There is no other real DX around, at least not with me, so I think 10m propagation is poorer than on Wednesday.

Yesterday 4X1RF was spotting CN8LI at a distance of 3860km on 6m - a very good distance, probably multi-hop Es or even F2.

I may QSY to 6m later to pick up any Es around on that band. In previous years I've managed CN8LI on 6m with an ERP of around 1W..
