Custom badge in posbit_legacy for users with > X posts per day?

[TrickyD]

If someone has a few extra minutes and could help me do this I'd greatly appreciate it.

I already have a code in my postbit_legacy that gives a user a badge if their join date was prior to a point X as

<if condition="$post['jd_dateline'] + 31536000 <= TIMENOW">
<img border="0" src="http://www.utopiafootball.com/images/pridestickers/veteran_3.gif" alt="Veteran" vspace="1">&nbsp;
</if>

But I have not been able to figure out a similiar conditional statement for displaying a badge for users with over a specific number of posts per day.

I'm basically looking for

<if posts_per_day > 20>
Display image
</if>

Can anyone offer that code for me?
