Two more cases for Laurie:
(20cm5f2cm) 5 fibres spread across a 20 cm wide strip, as before, but make the strip 2cm thick (instead of 1 cm).
(20cm6f) 6 Fibres spread across a 20 cm wide stirp.
(20cm5f2cm )14.7% (compare to 20.5% for a 1cm-thick).
(20cm6f) 23.5%
As usual.. increasing the number of fibres helps (as always) and having a thicker counter helps. But you're better off having two 1cm counters than a single 2cm counter.
And, of course, these multifibre strips are probably a pain in the ass to manufacture.. but I'm no expert on that.
