I agree with CainIV - that's the primary metric for judging progress. Everything else is supporting details, useful for staying pointed in the right direction.
One suggestion: Be aware if there are seasonal ups and downs that might affect how progress should be evaluated. If seasonal variations are large there might sometimes need to be "expectation corrections" (which can work in either direction) when your work is being judged.
