Noise Threshold progressive reporting in Message Log working on occasion in same scene, why ?

[JezUK]

I'm using pretty much the default render settings for Progressive Rendering V-Ray Adv., and in my scene I see the progress of Noise Threshold in the Message Log for only *some* of my camera views ??

Why is this happening ?

I would like to see the progress of Noise Threshold during rendering for *all* of my renders. Is there a reason this would be happening when it is *only* a different camera, a different floor level (admittedly a view which definitely has more noise in it) but it is still the same scene file......

The progress should always be printed; there is no reason for it to be missing. If you can give me the specific steps to make it not printed, it will be helpful.

Best regards,
