Sorry if this seems like a simple question but I have a leak playing 3bet pots from the blinds.

1 - When post-flop, in general, are we betting a larger sizing than we would IP?
2 - Are we, in general, betting at a higher frequency?

For example a hand I recently played

AhTh, SB v MP

FLOP - Jc7h4s

I tagged the hand and have myself betting 2/3 pot with 54% of my range.

3 - Does that seem reasonable?
