Old 8x10 film... compensation. HP4

[vpwphoto]

Hey we don't need to be too scientific here.
But I have a 8 year old box of 8x10 HP4...
It was in the freezer up to a year ago...
I am going to dust off my Vitax and shoot my kids...
Do you think I should rate it slow... etc because of the age..
...just give me a ballpark impression as I am shooting with a un-timed studio shutter or a Packard....

I have some HP5 from 1980s and a few years ago when it tested the film it was EI 125 or so based on where the 0.1 point fell above the very dense base fog.
