Thanks for pointing that out. I'll have to re-visit my assumption regarding bundled shares. 

Oh wait, both ChatGPT and Gemini are telling me that the cost function for LMSR is path independent.  So executing a bundled trade using multiple single-outcome trades only costs more because of transaction fees, not because of the probability paths.  If that's the case, my calculator is fine, since it ignores fees right now anyway.

That makes sense as a choice to make for your business.  But it also means my calculator is wrong because it uses a bundled price.  Something I'll need to go back and change.

(I guess the user can replicate it by buying one share at a time, but that is way too much work; also racks up transaction fees.)
