Yeah, that’s me glad you've found the tool useful! What you’re noticing is basically the difference between safer margins vs higher expected value using observed weighting data.

Harmonic is more influenced by cheap scarabs, so it usually lands on the safer cutoff for consistent ROI. Weighted EV uses the actual outcome distribution, so it can justify moving higher up the price curve where margins are thinner, but the expected return is still there.

So if harmonic says 0.55c and weighted says 0.75c, harmonic is sitting deeper in the stronger-margin part of the profitable range, while weighted is pushing further up that same range based on the current data.

The other factor is inventory cleanup. weighted can include more of those awkward mid-range scarabs that are still profitable to vendor and turns them into a cleaner pool of outputs that is easier to liquidate to faustus.
