The Stewmac calculator tells you what the fret centers should be , and you use a scalpel to scribe the lines.
Is the (minimal) increase in accuracy worth the extra hassle ? Probably not.
Is any luthier going to lay out the money for a set of Johansson gauges ?
Definitely not.

And here I was sure you had risen to defend the accuracy of inexpensive digital calipers!
It's not that you can't get something like gauge blocks that will show you where the location is to a greater accuracy than 1/100th of an inch. It's that by the time you line up all those blocks, mark, and use the mark to saw the slot you won't be any closer.
