How Tight is to Tight

[scott2130]

The other day a fellow 2+2er tracked me at 24 VPIP blah blah before the flop. He told me I should be 15 - 18 and needed to tighten up. He even went as far as sending me a spreadsheet to follow and bring my score down.

Is he right on the score being that low? I think trying to tighten up threw my game off because now I lost my edge and money. I guess it could be that down swing everyone is talking about because my cards do seem to be improving.

Is it ok to be a SLAG instead of a TAG as long as I'm not a [censored]?
