Description

According to the manual, there are two presets, "preset" and "quality".
   name     vector  step factor stretch shrink
   preset           0.50 1.00   2       2
   quality  default 0.50 1.00   2       2

“The smaller the step, the more instances of a font we get, the better it looks, and the larger the files become. It’s best not to use too many stretch and shrink steps. A stretch of 2 and shrink of 2 and step of .25 results in up to 8 instances plus the regular sized one.”
