[urq] WR valve clearances

Quick question for you because I have a mental block and can’t think straight about this:
I have to check the valve clearance gaps on my WR. The late Phil Payne’s excellent website has charts for warm and cold engines.

I will be doing my head off the car and so cold. The two charts show wider gaps for warm engines than for a cold one. Is this right or should it be the other way around? On a cold engine, won’t the gap shrink as the components warm up? So wouldn’t you want a bigger gap when doing a cold engine to allow for the fact that the gap will close up as the parts warm up?
Can someone please put an end to my confusion. I expect Phil was right but I can’t see the wood for the trees.
Many thanks

Keith
