This assumes that letter-shapes are only acquired during a fixation (and
not during saccadic leaps). I assumed that Bouma timed fixations and
leaps. Did he measure "letter-shape acquisition time"? You can flash a
letter on a screen. The flash time could be just a few milliseconds, and
a few seconds after the flash, the subject may be able to verbalize the
letter. If the minimal detectable flash time is shorter than either a
fixation or a leap, letter-shapes could be acquired during leaps in
addition to just fixations.
All such considerations could be made moot by the arguments in my
"Boumas - vision - unsharp"
