It is characteristic of this propagation phenomenon between NA and AS on 6m that the opening between any given pair of stations is brief: One or two minutes is not uncommon.
That depends a LOT on which part of the US and which DX country. Here in NorCal and other areas along the West Coast, JA openings often last 30-60 minutes, and often local to specific grids, and shift around over time. This is litle different from the double-hop openings from here to eastern NA, except that our openings it to northern EN and FN grids tend to be short, few, and far between. And similar to your JA openings, our EU and AF openings are VERY short and very rare. You're very lucky if you have prop long enough to wait through one QSO, then start and finish your own. I had that experience yesterday with CU2AP, my second EU (first was EA6). I wasn't sure that he copied my RR73, but I copied his R and my report, so I logged it. It was on LOTW the next morning, so I guess he did. :)
Rapidly changing propagation is a characteristic of 6M. Understanding that explains a lot, including all the concerns about signal reports that vary a lot.
