Yes, I'm seeing something similar. I'm running on AIX NetView 715 Fixpack3.
The graphs did not look right for me when I started monitoring a router with a Gigabit interface and a Bandwidth 200000 (200 Mbit)
statement. The previous router, which had a bandwidth 100000 statement, was graphed correctly.

I'm using an entry in mibExpr.conf namely
BandwidthUtilOut \
"8*100* ifOutOctets / ifSpeed" \
        . \
        . / \
        800 *

I tried dividing the ifSpeed by 800 first and this gave more believable results.
Your mileage may vary. I tried using:

NewUtilOut \
"ifOutOctets/(ifSpeed/800)" \
        . \
        . \
        800 / /
