I try to do the same. I often bid from my mobile phone when I'm away from home and try to get a bid in at the very last moment. Of course, it also doesn't help the adrenaline factor when my mobile phone decides to lose connection in the final moments. Argh!
It's always annoying when you lose out by a couple of pounds, or whatever. "Maybe if I'd have just gone that bit higher..."
Ah well, life's full of regrets :-D
