Well it's not standard practice on the other auctions I've listened to online - the DNW ones for example, where it is abundantly clear what's going on. The auctioneer reads out the bids as they come in, and whether in the room, from the phone or over the internet bid. As soon as a few seconds, he'll say "last chance, fair warning", then bring the hammer down with "sold" and saying briefly where it's gone. You aren't left in any doubt. Same with Spink.
If no bid he starts at the lower reserve estimate or even below that if still no bid. Says something like "shall we start at?" or words to that effect. Or if there is a bid, maybe, "I've got an internet bid of £700".
I really must attend one of these auctions in person at some point.
