by a factor of 110*

It increased it by a factor of 110. See: http://www.physicsclassroom.com/class/momentum/u4l1b.cfm

After looking at that page you should see that Force and Time are inversely proportional when dealing with impulse and momentum. That means if the force went down by a factor of 110, the time must have gone up by that same factor.
