LogicPD OMAP-L138 power consumption in DEEPSLEEP mode

I've been measuring power consumption of the LogicPD OMAP-L138 SOM using Wattson and was wondering if what I'm seeing is typical.  The SOM has been modified slightly; we removed the SATA and Ethernet PHY chips to further reduce power consumption.

            |  5.0V |  3.3V  1.8V  1.2V |   Sum  Loss | Efficiency
------------|-------|-------------------|-------------|-----------
 Running    | 648.6 |  61.9  61.1 251.8 | 374.7 273.9 |    57.8%
 Deepsleep  | 156.3 |  60.9  12.9   8.3 |  82.2  74.1 |    52.6%

The 'Sum' column is the sum of 3.3, 1.8, and 1.2V columns.  The Loss column is the 5V power consumption minus the sum of the other three voltages. 

I'm curious if anyone knows if these numbers for DEEPSLEEP look reasonable and if there is anything that can be done to improve these numbers? 

Thanks,
