Originally posted by Andrea K SPOT or Select on central point are equal, at least on k-1, I checked. it's a bad translation or a wrong sense of the phrase.
Originally posted by stevebrot I tend to agree. The phrasing is clumsy in regards to the comparison with "Select" setting, i.e. "a set of middle AF sensors in autofocus operation". Whether this refers to apparent size in the overlay or the actual sensor diameter is not clear.

Are you sure? This is the immediately preceding paragraph:
“Choose a focus point with the
narrowest in-focus area
When you have a desired focus point in the image field, choose an AF setting with the
narrowest in-focus area. For instance, when you set the AF mode to AF.S (Single), you have a choice of Auto, Zone Select,
Select and
Spot settings (in order from
widest to narrowest areas).”
That reads as a clear, direct and emphatic statement to me, not a clumsy translation.
Combined with the distinction between ‘single’ and ‘set of’ in the following paragraph it reads to me as Pentax clearly saying Spot is smaller and more precise than Select-Center-Point.
“Highlight: The advantage of Spot setting in AF mode
The Spot setting is an autofocus mode that detects the in-focus point using a
single AF sensor positioned at the center of the image field. For PENTAX digital SLR cameras marketed after the PENTAX K-3, the
Spot setting detects an area approximately 30 percent narrower than that of the Select setting, which uses a
set of middle AF sensors in autofocus operation.”
