the whole process from the time I got off my bike in the Thai side parking lot to getting back on my bike and going back home was 30 minutes exactly. This included everything including the 3 IO's and 2 bus rides.
The 1 minute refers to the amount of time waiting for the bus after getting my entry and exit stamp on the Laos side.
It was a very efficient and quick process. Faster than I anticipated, but there were 0 people in line on either side each time I had to go to the IO. I was there about 10:30 in the morning.
