Does this arb make sense?

[jtuck]

Rafael Nadal to win in 4 sets +400
Rafael Nadal to win in 5 sets +500'
Roger Federer to win -155

I cant see Nadal winning in straight sets

To give you a better idea of what your looking at...youd be risking $160.32 to win $4.19 which equals out to about 2.62% ....And if any commision in involved your gonna get hammered on that too.
