HP5 in Pyrocat-HD

Does anyone have some good starting times for HP5 in Pyrocat?

I'm at the cottage and the only developer I have with me is Pyrocat, and I thought I'd brought all FP4 (which I normally develop with it), but one box was HP5.... and I have no times etc for it and I'm having trouble tracking a starting point down online.

So if anyone has a good starting point - 20c, trays or btzs tubes just for silver or scanning, no fancy alt stuff - let me know (I tend to do the constant agitation thing, rather than stand and so on)

thanks!

(and getting hold of another developer isn't really an option right now)

I develop, in trays Pyrocat HD 1:1:100, HP5 two minutes more than FP4. My times @70F are 13 minutes and 11 minutes for HP5 and FP4 respectively.

Tim,
I don't use the HP variation but the MC which i think is so close anyway.
My time with HP5+ is 18 minutes @ 20C 1+1+100 1 minute initial agitation in a Jobo 2521 and then 10 seconds every 5 minutes. Looks good in a Beseler 45 with condenser head. Hope you can use this.
