How long does it take you to install a cartridge?

I have spent a at least a few to several hours installing a cartridge from beginning to end on my VPI table and was wondering how long it takes others.
It usually takes me a whole afternoon to install one and than a few more days afterwards to make fine adjustments.
Installing and doing a rough setup can take 30-60 minutes. You can spend the rest of your life refining the setup.
