I was doing some testing the other day and it dawned on me, that I do things COMPLETELY different.
When I need to test wicks, I pour 1 jar with my wax/fo/dye combo as usual with NO wicks.
Once the wax is fully cured, I drill a hole out for the wicks. I cut the tab off the wick, place in the hole, heat gun it a second to fill the small bitty void, trim and light.
You can now test one size, if it does not work, level the top off, pull the wick that didn't work out, replace with another size and test again.
I've done this for years, and it makes testing SO much faster and easier. Bruce Campbell from Wicks Unlimited taught me this years ago. I have saved so much time and money it's probably not funny. I hate testing wicks, so this method goes fast and is very easy on resources.
