The Chelsea Open Mystery Cache

The cache is a short hike from the Larrimac golf course, or if you are not in the mood for a nice walk to chase a little white ball, there is a less strenuous method of finding the cache which can be considered a park 'n' grab. (Not the original intent) It is placed to be winter accessible no more than a dozen meters off the trail. (Edit: Since the construction of the road, it is mere metres from a safe spot to park.)

Many thanks to royfran for bringing the changes to the area to my attention and the missing cache to may attention and replacing it with a new model.

The cache is at N45 AB. CDE  W075 FG. HIJ (use photo of course record available in the gallery and wikipedia)

A- Digital root of last 4 digits of the club phone number.

BC- Shots taken in back nine of record round.

D- Digital root of the number of strokes that Tiger Woods won by when he won his first ever masters. Subtract 1 from your answer.

E- Number of shots on first hole by Shields on record day. Add 3 to your answer.

F- Most common par for a hole on the course.

G- Number of the month that the record occurred on + last digit of the year that it occurred.

H- Hole on which Jeremiah Shields shot a 2.

I- Handicap on hole 7 (use leftward most value). Subtract 1 from your answer.

J- Most shots on a single hole in record outing. Add 2 shots to the answer.

Now, this is an important step. Due to construction in the area, the cache had to be replaced after the original GZ "disappeared". Subtract .010 from the north coordinates and .025 from the west coordinates of your calculated final.
