Frequency and Amount of dosage input.

I've lowered my dosage of ritalin(SR) from 40 mg three times a day, ( 120 mg a day total.)
To 20 mg four times a day, (80 mg total per day.)
Taking the medication 4 times instead of 3 times with a lower dosage.
The interesting issue I have is, that I seem to read better now at a lower dosage. Does this make sense?
Does anybody know if to much ritalin can cause some type of impairment if the dosage is to high.

Too high of a dosage has similar effects to being unmedicated or undermedicated. Symptoms return, hyperfocus is very prominent, can feel dazed, tired, unmotivated.

It makes sense that a lower dose could help more than a higher one, for that reason. Also, I've read that inattentive adhd is usually best treated with lower doses of stimulants than hyperactive or combined type.
