The scrollHeight minus clientHeight probe on an overflow: hidden page is a neat trick, since counting PDF pages really would miss the cut-off 60-item table you describe. Pinning the probe copy to 7.5in wide so text wraps like it does on paper makes sense too. Have you noticed any difference in measured overflow when a form uses a web font that loads late, or does the virtual-time-budget flag cover that reliably?
