Back in the 70s & 80s kids were, on-average, given 30mg instant release of Ritalin a day to start. These days they’ve cut that starting dose down to 5mg 2x a day for IR and the long acting is 10-20 once a day depending on the child’s weight.
Dosage back then was also determined by severity of “undesired” symptoms instead of other factors like body mass and how well a lower starting dose is performing.
This is probabaly largely due to the dosage.
