Steve,
114% for the iowait is cumulative so perhaps it is not a totally accurate
figure compared to the two individual cpu stats.
Also the procps-3.2.1 TODO doc mentions:

Supply better data for top's CPU state display. Currently top has
to subtract old numbers from new numbers and divide that result by
the number of processors. The kernel won't even supply the number
of processors in a portable way.

btw how do you display iowait? No mention of it in man top.
hth,
keith.
