Sarin vs. AGS Report

[wake2wake]

I am looking at a stone, and notice that there is a difference between the Sarin report and the AGS report. With the AGS report, this stone gets an HCA of 2, and with the Sarin report, it gets an HCA of 1.5. The biggest difference is the crown angle, which is 35.2 on the AGS report and 34.7 on the Sarin. Is it normal for the variation between the 2 report to cause a big change in the HCA? The other parameters are pretty similar - what do people make of this?

0.734 ct I/VS1
Depth: 62.6
Table: 55.3 (55.0 on the Sarin)
Crown Angle: 35.2 (34.7 on the Sarin)
Pavilion Angle: 40.8

one of the scans is wrong.
34.7 to 35.2 is outside the margin of error.

The AGS numbers are considered the official numbers but that doesnt mean they are 100% because they are using sarin machines now :{

Anyone else have any thoughts? It seems like that difference is enough to change how the stone performs (at least based on HCA)

saw the other thread.. the IS looks real nice and the IS image trumps the HCA.
