Verify my Colpitts Calculator....

I was hoping someone here could take a look at the calculator I made for building Colpitts oscillators and check it for errors and give me opinions/suggestions regarding improvements because this is fairly new territory for me.

Thanks!

I wasn't sure about the 160Ω reactance part, but the way I understand that (which could be wrong) is that with more inductive reactance, more/thinner wire is needed raising the resistance of the coil which affects inductor Q.  I picked 160Ω for XL because I have seen a few oscillator examples that used roughly that value.
