Let me help a tiny bit more: until someone discovers a method of freezing time and counting the precise number of remaining viable viral bodies (otherwise the number would change while you processed the sample for the counting) in each experiment, an absolute study becomes a whole new project involving multiple samples for statistical analysis. The time, the expenditure, the lack of progress when so much progress is needed by humanity. We need comparative studies to direct focus at this time.
When mathematics and data are used in prediction we call this an 'educated guess'.
So, for those that might think I am daydreaming at $800 IPIX, please at least agree to call it 'educated daydreaming'.
