SPLITLUNC & LUNALUNC is Terra Classic (columbus-5). LUNA is Terra (phoenix-1). There is no redemption between them. Sending either ticker to the other chain does not arrive and is not a conversion. A price ratio is spot value only.
1 LUNA = — LUNC. Spot only. Not a redemption rate.
STAKE
Unbonding is a wait on that chain only. A stake on columbus-5 is not a stake on phoenix-1.
