Don't think its that bad. Extra stage on Thursday is good, even though it's in the dark.
Friday 2 stages.

Saturday it should be possible to go from Gartheiniog 2 to Dyfnant if you leave after the WRCs and definitely possible to go to Chirk Castle or why should that be impossible?

Sunday from Dyfnant to Great Orme should be possible too I think?

So my guess: QS/Shakedown, 1 stage on thursday. 2 on friday, 3 or 4 on saturday and 2 on sunday. So 8 or 9 stages should be possible? Not bad, last year: QS, 2 on friday, 2 on saturday and 2 on sunday.

Gonna miss Epynt though!!
