John-
Is there a problem with the epoxy not curing or are you just worrying?
If the epoxy sets up hard, your ratios are close enough. Bad ratio mixes will result in incomplete curing.
I've used WEST with pumps for 30 years or so, and I haven't had any problems.
If you have a couple of plastic syringes on hand, you can check the volume that each pump is delivering, to double-check.
Unless mixing a large batch, it would be tricky to use measuring cups with 5:1 WEST, IMO.
1:1 and 2:1 epoxies are a different story.

I do buy new pumps every few years, but it's not really necessary- you can clean the pumps if they get gummed up.
