Last meeting by three pairs of teams the same margin?

In Round 3 1962, Glenelg met Norwood at Norwood; North met Torrens at Prospect and Sturt met West at Unley. The last time these sides met before that round, all of those matches had been decided by 24 points:

Rd 19 1961 Norwood 12.20 (92) Glenelg 10.8 (68)
Rd 18 1961 Torrens 16.16 (112) North 12.16 (88)
Rd 19 1961 West 14.10 (94) Sturt 10.10 (70)

The only other occasion where three meetings had the same margin previous was Round 14 1963, as Port met South at Alberton, West and Sturt at Richmond and Torrens and Glenelg at Thebarton:

All matches were in Round 7 1963:
Port 11.16 (82) South 8.17 (65)
Sturt 14.11 (95) West 11.12 (78)
Glenelg 13.11 (89) Torrens 10.12 (72)

Another quirk was the meeting of West and Sturt at Unley and Woodville and Central at Woodville in Round 6 1967. Both of those matchups had a margin of 45 points at the last meeting:

Rd 19 1966 Sturt 17.25 (127) West 12.10 (82)
Rd 20 1966 Central 14.22 (106) Woodville 9.7 (61)

And in Round 6 1967, the matches were decided by the same margin again, with identical points!

Sturt 3.4 7.7 8.13 14.19 (103)
West 3.2 6.9 9.11 14.15 (99)
Unley, 8562

Central 4.4 7.7 13.11 15.13 (103)
Woodville 3.3 7.11 9.18 13.21 (99)
Woodville, 2036

Even the half time margin was the same, also 4 points.

Thanks for that Spelly, I'd love to see how you manage to come up with these facts, always an interesting read.
