Just been looking at these, in the second tier obviously:

1. 1954-55 3rd
2. 1953-54 5th
3. 1981-82 7th (67 points, 47 equivalent for 2 points a win)
4. 1965-66 7th (46 points)
5. 1963-64 7th (45 points)
6. 1959-60 8th
7. 1951-52 9th (42 points)
8. 1961-62 9th (41 points)
9. 1952-53 12th
10. 1962-63 14th

Bit depressing really when you peaked in the 50s and 60s.
