What I always suspected

[dianeduane]

nk(t+1) — nk(t) = w(k-1)(t)*n(k-1)(t) — wk(t)*nk(t) + sigma(k,1)*u(t) Or in other words:  Sniping is the best way to win on eBay.

But this point was proven long ago.

Proven how? Somebody has to do the research and crunch numbers from a whole lot of auctions in order to show whether sniping is truly more effective than other strategies or whether it just seems that way to snipers.

Many successful bids on eBay were sniped ones.

When you use a relative word like 'many', you have to specify what you're comparing to. Many successful sniped bids compared to what? And what's the source of your information?
