Small Control Circles

[pete.owens]

IIRC the increase of line thickness to 0.45mm (as well as the bold numbers and white outlines) are in Bruce Bryant's BOF amendments to ISSPrOM2019-2 specs.

And to render circles to that spec you need to specify a diameter of 6.45 mm in Purple Pen.

However 6.0mm is too small. For most events I find 6.35mm is too small too and usually use 7.0mm with increase in line thickness to 0.45mm.

And I use the recommended bold control numbers with 0.15mm white border line.

I also tweak the purple from the ISSprOM specs to make the contrast a little clearer.

(if you ran at Leeds University in the summer you got these tweaks on your maps - I suspect no-one noticed!).

Ahh, that explains why I enjoyed the race so much - I thought it was the planning!
