It was so quick (maybe 10 minutes) - I didn't have time to post long at 80, quickly took 20 on 2/3 and moved the stop for 1/3 to 70. I didn't expect it (especially long) - I was only alerted by the alarm when I got in.
Still think 1/3 may go some way up.
...stop to 00
I was busy and completely missed it! Argh, will have to wait around for a decent entry.
