Saying 'my scanner runs at 60K pps' means that it can show something, at some scan angle, when a computer is outputting points at 60,000 pts c.
     

          This may be a true statement, but it is meaningless. To be useful to laserists, statements about scanner performance must also indicate what images are being shown, at what scan angle, and how well they are being reproduced.

        Saying 'my scanner runs at ILDA 60K pps' tells the listener that 'this scanner can accurately reproduce all parts of the ILDA Test Pattern, including the circle just touching the square鈥檚 sides, when the test pattern is run at 60,000 points per second at a scan angle of 8 degrees or less.'
