How much edge in super fast structure?

[mjm]

Structure:

5 handed sng
1,000 starting chips
Blinds increase every 3 hands
Blinds start at 10/20 and double (20/40, 40/80, 80/160)

How much of an edge can a player who has sound sng strategy knowledge have in this type of structure even against random donks? Anyone got any example ROI's over a decent sample in this structure?

If you regard 100 buy-ins as a standard bankroll for sng's, would you want more to play with this structure? If so how many buy-in's?

Any thoughts appreciated.
