Yes i understand the post is about compounding mistakes. That said, it takes one HELL of a read to make folding preflop here the correct. IMO, it takes no more or a special read to fold the river with top pair getting 16-1 like you said. I could be wrong about comparing the two, but the point i feel strongly that they are similar, and since you seem skeptical about mucking the river for a bet, i think you should be more skeptical about mucking prelfop fo ra 1/2 bet.
