..and then applied to P2PKH and P2KH sigscripts: "the way this max of 72/73B applies to P2PKH and P2PK sigscripts is... P2PK is only <signature>, since this is <= 75 only one byte for PUSHDATA is needed, and then follows up to **73** bytes of signature data, meaning P2PK may take **74** bytes at most? and, P2PKH is <signature> <pubkey>, pubkey is normally 33B or for legacy uncompressed 65B, both push-datas are single-byte due to <=75B, and the signature may be **73B** so 1 + 73 + 1 + 33/65 = 108 or 140B sigscript max for P2PKH?"
