in theory, such a high investment in O/D SHOULD - but I cant prove it - encounter diminishing returns....based on ancient statements by admin
if so, then the last 30 minutes of O/D practice each day will produce less improvement than they would if the same minutes were used later in the season
Now, I suppose that might be okay if one decided that the quick surge in IQ was worth the lower return per minute, but that is likely an uncommon choice. On the other hand, uncommon does not mean wrong.
