This is a brief video that demonstrates setting up the J-Mate and how the Sun Seek application works. You'll notice that from the time I put the solar filter on the J-Mate until the time I took it off, ready to collect points, required about 1 minute. No backsight required.
Precision tests will come, but initial results look very promising.
