Ilkley's Aqua Mirabilis ALC: Bonus Cache

The cache has been placed as a bonus physical cache for those successfully completing the Ilkley's Aqua Mirabilis Adventure Lab Cache (see here).
The given coordinates are for a parking spot on Craiglands Road, the starting location for the ALC.
The cache, a square click 'n' lock box, may be found using the values for A, B, C and D collected from the first four stages of the ALC to enter into the formula for the final coordinates. It is a 10-minute walk away from White Wells where the ALC ends.
Look for the cache here:
N 53 54.(B+D)(B-A)(D-1) W 1 49.(C-2)(A-4)(D+2)
