James,
I am sure it was most likely coincidental, but my big "dry up" event occurred between weeks 8 and 9 at which time I was doing (besides kegals) a LOT of ladder climbing up/down working on our new house project... I was major leaking before and during, changing pads all the time, even at the top of the ladder... Then one day overnite things really dried up... go figure...
This is also the "average" time frame doctors mention for the change to occur also... so really do not know if it was the ladder, but I know the excercise probably helped... Maybe my brain->sphincter communication also telling it to shape up as it was getting tired of it wetting my body while on a ladder.... 
Another interesting observation, was that after the major dry up event, I was down to just an occasional dribble and was only using one small pad a day... At a doctor's visit, he told me to quit pads cold turkey and see what happed... I did not follow this advice as I did not want to get dribbles on my underclothes while I was working on house again... just changed the small pad at night for about the last 7-8 weeks. Recently, I had run out of pads one day, so didn't wear one and interestingly enough, DID NOT have a dribble all day! Should have listened to the doctor earlier... Anyway, I found myself and kegals "background thinking" about "hollding" and it worked fine... but I needed the LACK of the security blanket pad to get there... Maybe our brains/bodies respond better to necessity/discomfort to keep from getting wet than subcontiously lazy and depending on pads... Anyway, I am now pad free and enjoying it...
These have been my experiences and observations for me... everybody is diifferent, but felt I would pass on my experiences to you... For me, knowing better how my mind seems to work, I would have tried ladder excercises in the nude w/o pad to have "visual" feedback... 
God Bless!
