Default Compression test help.. 95 wrx

Is there anything I should add to this ...

1) warm up car
2) remove ignition fuse
3) remove packs & plugs (all)
4) Carry out test

I had warmed up car but has cooled as it's started to rain and had to leave it till it stops and was wondering if the car MUST be op temp to carry out test ?

Also if there is any technique to no4 above ....

Cheers

If the readings are in PSI then there's nowt wrong with the Comps as should be between142~171 psi .
