On several occasions I have tuned two pianos together for duo performances. Like you, I too tune without an electronic assistant (which like most assistants can be more of inconvenience). Over the years I have refined the procedure to get more accurate results. I now set the pitch and temperament in one piano, then set the pitch of the second from the first and put in a temperament. Instead of ironing out irregularities in each scale separately using forths fifths sixths and minor thirds, when tuning two pianos together I now check each note of the temperaments with the respective forth and fifth on the other piano. In this way it is possible to get the two temperaments to agree with each other very well indeed. I then proceed to tune each piano in the usual manner. At the end of the tuning I check the pianos from bottom to top playing each unison pair together, when small errors which are discovered can be corrected. Yes I know it's a bit of trouble but I think its worth it. As fees go, when tuning two pianos together in the manner described I charge the same as I would for two pianos in separate locations. After all, the cross checking will ensure that it takes more time than that normally taken, to tune two pianos at the same location. The travelling time saved will be used up with the extra cross checking. For what its worth.
