Personal Strokes Gained
Personal Strokes Gained (PSG) compares your current round's Strokes Gained with the average of all of your rounds to see what you did better or worse in your current round. This means that it is very easy to identify what you did better or worse compared to yourself and your own normal performance.
A value of 0.000 means that you are exactly average (meaning exactly the same level of performance as your own normal performance); a positive number means that you performed better than your normal performance; a negative number means you performed worse.
Over time, this is very powerful as it answers the question: Am I getting better? A positive PSG over the last 10 or last 20 rounds means that you are getting better; a negative one means that you are trending worse.
Let's look at an example:
In this particular round, this player was 1.001 strokes better than his normal round (1.001 PSG Total). That was distributed the following way:
Worse tee shots than normal (-1.068)
Better approach shots than normal (1.524)
Better chipping than normal (0.810)
Worse putting than normal (-0.265).
We can then break these numbers down even more to isolate:
Which tee shots were better/worse:
What distance brackets on approach shots were better or worse:
What shots around the green were better or worse than normal:
And finally, where on the green this person performed better or worse than normal.
It is sometimes really difficult to know if you're getting better or not, but Anova's Personal Strokes Gained analysis gives you a definitive answer.
