What does dispersion number mean?

[Ryan_luan@yahoo.com]

I took 10 shots using 7 irons. When I look at the shot history, the summary line shows the following data:

DISPERSION: 16.8 / 19.7 YD

Does anyone know what the two numbers mean?

I think they are length and width of the dispersion circle.

I don't own a Skytrak, but I would expect those numbers to be the standard deviation or average between your shots for Carry and Total distance yards respectively. What Colin suggests would be pretty cool, but I think unlikely since it would probably be a circle and only give either 1 or 4 points of data.

This is the 9 iron data after 12 shots. The dispersion shows 16.8 / 19.7 yards. Can someone help make sense the dispersion number?

Which column is yards carried and which is total yards?

[Ryan_luan@yahoo.com]

Sorry I don’t have the header row; but 128 and 134 are the average of carry and total - it’s column #7 and #9. Column #6 is left/right off line, with negative number being to the left.

I think that is correct

[JV17]

Yes, so assuming the 6th column is the offline number, than the numbers would tie out to length and width of a dispersion circle.

[Ryan_luan@yahoo.com]

Yes, I think it’s this. Thanks everyone.

The numbers are your CARRY and TOTAL distance dispersions, respectively.
