What is a "Good" BB won per hand from the Big Blind

[marching_on_together]

So i'm looking over stox's new book, page 101 shows a table for BB defense. The numbers given for the player identified as high (i'm assuming stox) are:

put $ in pot 51.12%
win % WSF 38.77
raised 11.15%
went to SD 33.12%
won at SD 56.78%
BB/ Hand -0.2

the other two good players are reported to have values of -0.3 BB/Hand

So my question is am i interpreting these numbers correct are these the BB values given under the position tab in pokertracker.

Am i correct that BB/hand is considering all hands played in the BB.

What do people feel is a good BB/hand value?
The put $ in pot of 51.12% seems higher than what i have seen before.

the single most important thing that is sometimes overlooked when examining results from the blinds is the number of the people at the table. If you lose money from the blinds heads-up yuo are not doing so good, as more players are at the table your winrate at the blinds should decrease.

I presume part of the reason the vol put in pot seems high to me is that most of the times when I have seen these numbers are from 5-10, 10-20 and 15-30 limits where there may be less raised pot than in your games.

I'm enjoying the book by the way, it's refreshing to see a book focused on short handed play and one which treats the reader as a peer with a very honest appraisal of the authors assessment of hands and situations.

Even if information isn't always new it's nice to have it written down for reinforcement sake and as a reference when running bad or good has affected your game.
