Eigeny please correct me if I'm misunderstanding this.

There are two completely different command sets here, the long commands that Ian learned and the super long commands Lee learned.

Different models of Daikin use the different command types. A single Daikin model would respond to just one command type, not the other.

There is a problem learning the long commands, but Eigeny and maybe other online sources have those commands in a form the Pronto can transmit.

The super long signals cannot be transmitted by a Pronto from a single string of Pronto Hex. I don't know whether you can use the long gap in the signal to work around that.
