Which vario has lowest latency? (Least delay to indicate thermal we pass)

Anyone has done side by side tests?

This interesting summary of the physiological delay of the visual system could be considered another reason a hypothetical 'instant' vario would be less than useful. If you like technicalities, that is.

Scientists have revealed the human brain has a 15-second lag that helps stabilize incoming visual information, which we don’t notice bombarding us in the course of our everyday lives.
Eyes tend to receive an enormous information load from dusk till dawn, and as one opens his or her eyes in the morning, the brain starts its intensive work, processing incoming pictures from the surroundings, including imagery from TV screens and computer monitors.

A team of vision scientists at the University of California, Berkeley and Massachusetts Institute of Technology (MIT) revealed this secret of the human brain: To save us from insanity induced by a constantly changing torrent of pictures, shapes and colors – both virtual and real world – the brain filters out information, failing in most cases to notice small changes in a 15-second period of time.

It actually means that what we do see is, in fact, a mixture of past and present. According to the research, published in the journal Nature Neuroscience, stability is attained at the expense of accuracy.

"What you are seeing at the present moment is not a fresh snapshot of the world but rather an average of what you've seen in the past 10 to 15 seconds," said study author Jason Fischer, Ph.D., a neuroscientist at MIT.
