I have been putting last minute bids into Ebay for over 3 years - though only recently using AS.
I used to use 20 seconds on my own system using a package called iSNIPEit (support went belly up - so I switched to AS).
I have dropped to 15 seconds because everybody on AS seems to want to push it really close, but having missed a bid I am inclined back towards 20.
I don't believe I have ever placed a single last minute bid at 20 seconds where I lost and in reviewing the auction I came to the conclusion that somebody outbid me manually.
Sure, I've been beaten by other snipers who bid after me, and by manual bidders who bid before me. And I've had my bid raised by a later sniper who didn't bid as much, and I've raised other bidders' bids to the increment (or less occasionally) above mine when they bid more than me.
But I have never encountered a manual bidder who placed a bid and was holding the high bid before my bid went in and who managed to get the high bid back after my 20 second bid beat his proxy.
The way I see it is ; I'm bidding once and late - my price is reasonable for the item (I'm not looking for individual bargains - I get the bargains overall by not being pushed all the way to my max on every item). If there is a manual bidder out there looking at the item - holding the high bid at somewhere below his/her proxy then he/she has 20 seconds to do a refresh - see the price has gone one increment above his/her proxy and that he/she is not the high bidder - then he/she has to type in a bid and get it accepted.
It certainly could happen - but I've never seen it.
I suppose a couple of times when I have been beaten by a later bid it is possible that a manual sniper was watching the prices at, say, $50 and planning on a certain bid (let's say $100) and then on seeing the high bid go to $90 as a result of my snipe he/she does a quick change and submits a $150 instead.
Maybe - but I doubt it happens much - If there is a manual sniper out there I would guess that he/she has already worked out the simple rule - one bid / bid your max and be happy when you're not pushed all the way.
P.S. the question is not whether someone could bid manually like this - it is whether people actually do on a regular enough basis to make me reduce my lead time to a point where I start missing bids.
But, I hear suggestions though nothing definite, that AS attempts to add a few seconds when Ebay gets slow just to be sure it makes it.
And sometimes I wonder about those Sunday evening quarter hour events and a tiny voice says 'maybe it's not Ebay that gets too slow but AS'. After all Ebay introduced the facility to time auctions like this - I would be inclined to think that their system staff did some analysis and continue to do work to ensure they are not tripping themselves up - after all inability to accept bids would upset their customers, the sellers.
(Really Sara, it's a very very very tiny voice).
(Edit)
P.S. I have just seen someone else propose this heresy ;
