wackamole convergence speed

I've got wackamole working great for ip failover.  Unfortunately, it's
working TOO great.  apparently, we don't want the address to fail over any
quicker than one minute.  apparently, we've got some networking issues that
we hope to sweep under the rug by not failing over at the first sign of
trouble.  is there a configuration parameter that will cause it to not fail
the interface over unless it's been a minute?
