How to ignore own IP in form entry conversions?

There is no code I am aware of to exclude those visits. The lead_count and view_count are not filterable. I'll tag this as a feature request as I know it has been requested before.

You could delete the entries which are from your IP by going direct to the database and selecting and deleting them there. On an ongoing basis, you could set up some sort of cron job to periodically delete the entry after it is created, if it was from your IP.

I guess more likely is that you need to delete the views from your IP rather than the entries from your IP, since there would be far more views from your IP than form submissions (when developing or testing the site.) Those views would have to be deleted from the $wpdb->rg_form_view table. The entries would have to be deleted from these tables:

$wpdb->rg_lead
$wpdb->rg_lead_detail
$wpdb->rg_lead_detail_long
$wpdb->rg_lead_meta
