Execution percentage difference in 'Execution Progress' widget and on Release Summary page!

Hi,

I have noticed that in Zephyr the Execution Progress percentage in the Release Summary page is showing a lower percentage to the one in the Execution Progress widget in the dashboard!

The release has 4 cycles,

example in total 409 of the 425 tests have been executed which = 96.24% which is what the Execution Progress widget (and all other widgets) show in the dashboard.

But in Release Summary page for the project/release the Execution Progress shows as 94.96%  (which if I add up the percentages for all the cycles it gives me this figure as a percentage) 

So my question, is this by design (which does not make sense if it is!) or is it an error/issue?

any one noticed or raised this?

Thanks
