Some are more equal than others

After hearing from several Cornwall councillors about how they see their role as effectively a full-time job, and work so many hours per week (at a rate below the minimum wage), I thought I'd try to analyse the performance of some of those seen less often at County Hall, based on meetings they were expected to attend over the past six months. Five of the ten are Lib Dems.
1. Bill Jenkin (unspecified) Camborne North - 33.3% 4 out of an expected 12
2. Michael Callan (Ind) Perranporth - 46.1% 6 out of an expected 13
3. John Oxenham (Lib Dem) St Austell Bay - 50% 2 out of an expected 4
3. Robin Teverson (Lib Dem) St Mewan - 50% 4 out of an expected 8
5. Paula Dolphin (Lib Dem) Flexbury & Poughill 54.5% 6 out of an expected 11
6. Nathan Bale (Lib Dem) Bude & Stratton 62.5% 5 out an expected 8
7. Neil Plummer (MK) Stithians - 66.6% 4 out of an expected 6
8. Bryan Preston (Lib Dem) Saltash Burraton - 80% 4 out of an expected 5
9. Lance Kennedy (Con) Bodmin East - 85.7% 6 out of an expected 7
10. Dave Saunby (Ind) Falmouth Trescobeas - 100% 6 out of an expected 6
The data presented above is taken from the council's official attendance register and does not take into account appointments to outside bodies. Neither is it a definitive guide to whether a councillor is hard-working or not - Lance Kennedy, for example, as a Cabinet member, almost certainly attends many more meetings than the six recorded. Similarly Falmouth's Dave Saunby features despite scoring 100% attendance for the meetings at which he was expected - it's just that he was expected to attend only six.
The data must also be read in the context of this explanation from the council:

Total expected attendances
The number of meetings that the councillor was expected to attend in their capacity as member of that committee. This only includes meetings for which the councillor's actual attendance status is known.
Present as expected
The number of meetings that the councillor attended in their capacity as member of that committee.

Some councillors are members of more committees than others. And I'm sure some councillors will protest that they work 24/7 on behalf of their constituents without needing to attend meetings. A table which looked at the other end of the scale, though, would almost certainly feature Lib Dem Chris Pascoe (Threemilestone & Gloweth) whose 97% attendance record is based on turning up for 35 out of an expected 36 meetings. That's nine times as many meetings as Bill Jenkin.
