Some of the pages in my client's website are with pageviews > 100 in a week, although the Avg Page Load Time is 0.00 sec
and if PageViews < 100 in a week, although the Avg Page Time is displayed.
I understand that timing metrics are based on 1% of data collected by default; I also read Google's documentation https://support.google.com/analytics/answer/1205784?topic=1120718&hl=en
But this doesn't explain why I am getting such data. Is this a sampling issue or something else?
