Changes here look good 👍🏼

While on the topic of ratio, there's a comment in calculateVCpusToMemoryRatio:

// normalize vcpus to a mebivcpu value

Should this still be mebivcpu even though the ratio is using GiB?

[bwagner5]

yep, should still be mebivcpus because it is still stored in MebiBytes, the input just defaults to GiB
