No - sorry Ole. I used 30 secs continuous initial agitation, then a single inversion of the tank every five minutes throughout the one hour. It turned out to be a futile exercise anyway but didn't want to leave a stone unturned as they say. The thought only occurred to me after reading a piece on Atget and combined it with the Digital Truth info.
I too remember reading an article on using Rodinal and Tri-X for very high EI values. I tried it at EI 1600 and for 22 minutes, with good results. If your results are any indicator, anything above EI 3200 will be fraught with problems.
