At 12pm am on the 12th the number was 10% more than Katrina
At some point in between the number was 10% less.
In fact, if you scroll down on the url you listed to the commentary on figure 2 you'll find
"Hurricane Ike at 12:30pm EDT had an IKE of 134, 10% higher than the value of 122 Katrina had at landfall in Mississippi."
The reason it jumps around is that the number is based on the windfield which changes. Recon flies in an x shape through the storm sampling winds to the NE, NW, SW and SE of the storm. This wind profile is then used to generate the IKE numbers which can be used to make such statements as above. All estimates of course and something akin to the Safir Simpson scale for wind damage. Ballpark-ish at best
