I don't notice them worsening things at longer time controls
either, but then again, I've never been a very deep searcher,
though things are changing.

I also understand that you do the full Hsu thing, so your
overhead must be a lot bigger.

If I find that with increasing hardware speed/slower timecontrols
it does start getting worse, I will uncheck the 'singular extensions'
checkbox and problem solved :)

I gather from this you won't be using them this weekend? Or is
90m SD also 'bullet'?
