Yes, the spread is larger, the density and thickness is lesser.
I got into this discussion with someone else.
Unless you have data released in the last few months... I believe the data which claimed the ice was thinner was based on a approximation using GPS data.
The accuracy of that data was questioned and they were going to come up with new measurements.
it really does not matter to me but here was one of the articles we were quoting.
from the ut article
"Antarctica was once buried under a deeper and more extensive layer of ice during a period known as the Last Glacial Maximum. Starting about 20,000 years ago, the ice began slowly thinning and retreating. As the ice mass decreases, the bedrock immediately below the ice rises, an uplift known as postglacial rebound.
Postglacial rebound causes an increase in the gravitational attraction measured by the GRACE satellites and could explain their inferred measurements of recent, rapid ice loss in West Antarctica. The new GPS measurements show West Antarctica is rebounding more slowly than once thought. This means that the correction to the gravity signal from the rock contribution has been overestimated and the rate of ice loss is slower than previously interpreted."

So in short the eastern mass is the same or larger.
the ice mass loss in the western mass has to be recalculated. To see if the mass is losing ice faster than typical during the 20,000 year warming trend.
That took about 20 minutes.
