Only Connect #56 - Guest Edition Mystery Cache

This is another in a Connection-style series of puzzle caches requiring a bit of lateral thinking. This one leads to an all too familiar magnetic BYOP final. The cache itself can be found at an appropriate (if misspelt) location. Thanks very much to Jesmond Lynam who's trusted me again to continue to expand his excellent Only Connect series of puzzle caches.

The rest of the series can be found by clicking on this link to the Only Connect bookmark list.

To find the final coordinates for this cache you'll need to solve the cryptic crossword clues below and then find a link between them. Once you've found the link then each clue will give you a name. Use the names as described below to calculate the final location.

Clue 1: Confused bat won out concerning settlement (5,4)
Clue 2: Blue question mark is certainly a puzzle! (7)
Clue 3: Article's location regarding a place of entertainment (7)
Clue 4: Transport fence component along old road (7)

A = The number of letters in the name linked to clue 1 (2 words)
B = The number of letters in the name linked to clue 2 (1 word)
C = The number of letters in the name linked to clue 3 (1 word, the short version)
D = The number of letters in the name linked to clue 4 (1 word)
E = The number of letters in the name of the elderly, practical writer that connects them all (2 words)

The final coordinates are:
N54 57.X
W001 34.Y

Where X = (D + E) x B x C
and Y = (A x D x (B - C)) + E
