i've talked with someone at verisign personally. they don't even know when domains get deleted. sometimes they stick around for a year after the expiration date, sometimes they're gone quickly. ever notice how ones that have some sort of value just hang out there? it's bullshit.
i asked him, if it's an automated process and the registry engine does it, how can nobody know? he was fucking clueless.
it's just more corruptness in the netsol/verisign space. it's bullshit. no other scripts or companies can help you, verisign owns the master registry. everything else is a sham. the bidding places probably just help figure out which domains are popular so the owners can take them and resell them
