Howdy,
I'm facing a bit of a strange situation. We determined the value for a parameter experimentally about 3 months ago. The value we determined works well. Just the other day, I found a reference that gives a theoretical basis for why that value works. This is pretty handy since the experiments are no longer the only source of justification for that value.
However, when writing this up, it might look a bit weird to say "we figured it out experimentally, but then found a reference that backs us up". To me that would seem like we just arbitrarily guessed but then happened to guess right.
How would I go about discussing this? The theory and the experiment are very close, but not exact, but it's still weird :-P
