Good reply & yes that made perfect sense to me, thanks!

Those mechanical problems and the incremental repair jobs are a valid explanation to me. Its good to know that they're able to reach 80" now. The maximum depth I've seen in the log files was 77", although I have to say that I only started to pay attention to depths after reading several files, so its possible that greater depths are reported... Anyway, the main thing is having the boat ready for the job, since it is, are the divers working on the Juno site now (as much as possible & weather permitted)?

Your post provided me with enough new information to work with, so I have to revise my expectations. Before your reply I could only work with the information I had, and that made me sceptical about Juno, in fact I called it a bust in private conversations. I have to stand corrected then, no sweat, I'm not a rusty thinker, I can adjust easily and create new thought patterns on the fly with this new info at hand. Most valuable, thanks again for your reply!
