Your one observing a correlation between kindergarten and success? No, I think your comment was likely to engender in the typical reader a belief that kindergarten was known to have a significant and positive causal effect (both statistical and clinical) on outcomes as a general rule. I don't believe this has been established. My intent in responding to your comment was to prevent that belief from wrongly being engendered in the minds of the readers.
