The 500K lovelace floor was set higher than the natural fee for both
inlined (~340K) and ref-script (~242K) Plutus V3 spend txs. With it
in place, every script-spending tx pays the same 0.5 AP3X regardless
of whether scripts are inlined or referenced — masking the on-chain
size reduction of ~3.4 KB / -82% per Claim/Submit/Accept measured
end-to-end on Vector L2 testnet.
200K is below both natural fees (so lucid's auto-estimate wins) and
still ~5x above the lucid-evolution 0.4.30 ~5K under-estimate the
floor was originally guarding against.
Expected per-cycle saving on Vector L2 testnet: ~0.32 AP3X
(Claim: 0.34 → 0.24, Submit: 0.34 → 0.25, Accept: 0.35 → 0.23).
