I did not realize that the new version of JoinMarket does not output to the terminal just logs. So I had to clean my UTXO. I moved each UTXO to a new address, to ?untaint? them and I managed to coinjoin as a taker with absurd_fee_per_kb=925000.  The price was bit high maybe I had set the number of makers, ?N?, too high or maybe the increase is due to the new market value for transaction fees.  I am still tweaking parameters to try to coinjoin as a maker.

How many times, is N used for different parameters? It sounds as though, N represents at least the the target block confirmation time and the number target makers simultaneously.  Perhaps that's theoretically acceptable if each lives in a different namespace, but from a practical perspective why would anyone want to obfuscate that?  I will reread the high level design to rule out the possibility that maker coinjoin attempts are not failing due to something with the protocol.
