My take is that Leo realizes he can't be a loose cannon in the info dept, especially if DF took exception with an earlier PR that put out more info than they would have allowed.  I understand his position and feel as long as he is coming across with his understated, calming air of confidence that all must be well in CTIX land.

I guess the time to start worrying is if  he should become  unavailable all of a sudden for a matter of weeks or months.

I for one am very impressed with how much of the focus is on matters that only come into play once we establish a very successful P1 (MTD).  I think those close to the action are feeling pretty confident with a successful end to this part of the trials; sure hope this is a correct read on the situation.
