2012.3 Vivado Timing Analysis - Why is the MMCM/PLL compensation value different than the ISE timing analysis?

Why is the MMCM/PLL compensation value different than the ISE timing analysis?

In the Vivado tool, I get the following:

MMCME2_ADV_X0Y3 MMCME2_ADV (Prop_mmcme2_adv_CLKIN1_CLKOUT0)
-2.861 2.568 r mmcm1/CLKOUT0

In the ISE tool, I get the following:

MMCME2_ADV_X0Y3.CLKOUT0 Tmmcmcko_CLKOUT -3.361 mmcm1
mmcm1

This issue is scheduled to be fixed in the next major release of the Vivado tool.
