Following Jonathan's comment, it's worth showing the other combinations of place bells in the 3-4 position - those in which one or both bells are ringing one of the "exceptional" place bells, i.e. 2nd, 3rd and 5th.
Two of the combinations have a stretch of coursing below the treble:
The others include 3rd place bell for either bell, and the symmetrical lead.
Jonathan asked whether the leads in which 3-4 course below the treble have the smallest separation of any leads in Cambridge Maximus. This is true: here is a table showing the average separation for every lead, as well as the average over a whole course for each position.
Pair | Lead 1 | Lead 2 | Lead 3 | Lead 4 | Lead 5 | Lead 6 | Average |
1-2 | 1 & 2 : 2.83 | 1 & 6 : 2.67 | 1 & 10 : 3.75 | 1 & 11 : 4.33 | 1 & 7 : 4.00 | 1 & 3 : 1.50 | 3.33 |
3-4 | 3 & 4 : 4.13 | 4 & 8 : 2.00 | 8 & 12 : 2.25 | 9 & 12 : 2.08 | 5 & 9 : 1.17 | 2 & 5 : 5.58 | 2.62 |
5-6 | 5 & 6 : 5.21 | 2 & 10 : 2.17 | 6 & 11 : 4.50 | 7 & 10 : 4.08 | 3 & 11 : 4.50 | 4 & 7 : 4.92 | 4.17 |
7-8 | 7 & 8 : 2.96 | 3 & 12 : 3.92 | 4 & 9 : 5.50 | 5 & 8 : 4.42 | 2 & 12 : 4.67 | 6 & 9 : 4.58 | 4.32 |

11-12 | 11 & 12 : 1.79 | 7 & 9 : 1.75 | 3 & 5 : 2.88 | 2 & 4 : 1.58 | 6 & 8 : 2.67 | 10 & 12 : 2.75 | 2.19 |
