[RSS Feed/News] postbit thread count?

[XenForo]

Does such thing exist? I'm trying to essentially use this:

XF 2.1 - Is it possible to add message/like ratio on postbit? ​

I need something like that. For example user has 100 messages and 200 likes. His ratio would be "2" and added on postbit. For example: Nickname -Avatar- Location: London Message Count: X Like Count: X * Message/Like Ratio: 2 *

xenforo.com

what i would like to do is something like this:
PHP:

       <xf:if is="$user.reaction_score">
<dl class="pairs pairs--justified">
<dt>Thread/Message Ratio</dt>
<dd>{{ number($user.thread_count/$user.message_count, 2) }}</dd>
</dl>
</xf:if>

is there a way to do this via the postbit?
