100% is way wide of the mark... our CB pairings have been to say the least interesting. At a conservative estimate we've used 9 different players, a couple like Ballard and Curran, not really significant as only getting a matter of a few minutes.
We've used 12 different pairings, of which Baudry Fryers have 8 matches, Conroy Baudry next with 7. Baudry Fryers have some decent results, but so have a lot of the other combos. For instance probably our best result thus far was winning at Home Park.... a Grant Fryers combo.
What makes it so interesting is that conventional wisdom is that in a successful side having a solid stable CB combo is a prime requirement.... and we've not had that.
I find your figures to be a bit wide of the mark.
I make it out that we have had 10 different pairings at CB using 8 different players there.
9x Baudry & Conroy with w5 d2 l2 conceding 11 goals with 2 clean sheets.
8x Fryers & Baudry with w6 d1 l1 conceding 5 goals with 5 clean sheets.
4x Baudry & Zakuani with w1 d1 l2 conceding 6 goals with 1 clean sheet.
3x REG & Baudry with w2 d0 l1 conceding 4 goals with 1 clean sheet.
3x REG & Fryers with w2 d1 l0 conceding 2 goals with 1 clean sheet.
2x REG & Broadbent with w1 d0 l1 conceding 2 goals with 1 clean sheet.
2x Fryers & Conroy with w1 d0 ll conceding 2 goals with 1 clean sheet.
2x Fryers & Grant with w1 d1 l0 conceding 2 goals with 0 clean sheets.
1x Fryers & Zakuani with w0 d0 l1 conceding 2 goals with 0 clean sheets.

It shows that Fryers and Baudry have easily the best partnership for keeping clean sheets with 63% of games they have played in as a pairing ending with us not conceding.
