Cannot count in repeater

Looked in the code and saw $alm_loop_count so I used that ??

<?php if($alm_loop_count == (($alm_loop_count-1) % 3 == 0)) {echo '<div class="row activity-row">';}

       //looooooooooop

    if($alm_loop_count % 3 == 0 ) {echo '</div>'; }
 ?>

Nice find, yea all the available template variables are listed here – https://connekthq.com/plugins/ajax-load-more/docs/variables/

$alm_loop_count is not listed in the documentation.
