I smell a new iphone app! Love the title! Aren't you supposed to be the one recieving the gifts? I love the smell of D-plane in the morning!
 
Most viewers, but not all viewers, will know how to download the excel file (see the Save File Excel in upper right corner). Some will not know how to use spreadsheets and may not have Excel on their PC's.

If you don't have Microsoft Excel, you can download Open Office (Google it), which will allow you to
use the spreadsheet by entering different values in the cells.

Brian, there is a problem with this spreadsheet. The sheet is not Protected, therefore, the user can accidentally
enter a value in a formula cell and lose the formula. I suggest making the entry cells a different color from the
formula cells. Then remove Protection on entry cells, right click | Format | Protection un-check Locked. Now change the Formula cells to Locked using the same steps. Finally, Protect the Worksheet and/or Workbook,
Tools| Protection Worksheet or Workbook or both. Save file and you are good to go.

Impressive!
 
Does anyone know the approximate differences in the VSP through the bag? 2*-3*? I understand that the numbers can be different from player to player (even swing to swing!) I just cannot believe how far right you have to aim when hitting it 5* on the up!:eek::eek:

It's my understanding that the VSP can range from ~40* to ~65* through the bag.

Not sure about the exact increments.
 
At the risk of sounding like the dumbest guy on the forum could someone confirm that the distances are measured in yards and whether the formula for the aim adjustment stays the same if the shot length was in metres instead of yards. I'm assuming it wouldn't because the distance/radius would be longer (10%), therefore the length of the arc would be longer, therefore the adjustment greater. Obviously the result would also be greater (10%) just wondering if it could somehow maybe need a differnet formula. Unfortunately its a long time since I did any math(s);)
BTW what is CP short for? (obvious what it means, but not sure what the letters stand for).

Should the vsp be close to the lie angle of the iron?

Depends on how much more vertical your shaft is in the latter stages of the downswing (ie coming into impact) than it was at address. If your clubs are fitted to your swing I would guess that VSP and club lie angle+a few degrees would roughly correspond.
