So, right off the bat (sorry!), your notation seems to say that there is a derived strong inference between 5r3c1 and 8r3c5, which therefore implies -8r3c1.
To get there the long way around, I guess I would have written the AIC...
5r3c1 = 5r9c1 – (5=7)r9c5 – (7=8)r3c5 => -8r3c1, and maybe combine the last two nodes into an ALS...
5r3c1 = 5r9c1 – (5=78)r39c5 => -8r3c1.
But your notation is really following the AIC around cell by cell and noting that the three true digits (578) resolve the three cells, r9c15,r3c5. True digit 8r3c5 can then “see” 8r3c1. Is this the right idea?
