XF 1.2 Another conditional question

[RaymondCC]

I've placed the conditional code below in "message" template to show an Ad on the last line of the first post.

<xen:if is="{$post.position} % {$xenOptions.messagesPerPage} == 0 AND !{$message.conversation_id} AND !{$visitor.user_id} AND {$thread.reply_count} > 0">

The conditional only shows an Ad on the first post.
How can I modify the conditional so that the Ad shows on the first, second and third post? (Google only allows 3 AdSense unit per page)

Thanks.

Personally I would use three separate code blocks, changing the post id for each one, to allow for tracking.

Wouldn't that somehow slow down the processing of the page?

No.
