Understanding % RDY / %CSTP scale

Hi

I am now starting look at our VM estate rather than just let it run and hope for the best!!

I was looking at the metrics from ESXTOP and see some of the suggested values like 10 for %RDY, I had a quick question on the scale that ESXTOP is displaying the numbers in.

I am currently looking on one of our hosts at the VM's and see that the %RDY stats range from 0.13 up to 0.62

I wasn't sure If  0.13 is  below 1% or if that is actually 13% what's the scale?, as from my reading based on a single vCPU one is good the other bad.

I was expecting the below but now i'm not so sure.

1.00 = 1%

13.00 = 13%

Thanks
