I understand that "Nodes at Extremes" are a necessary part of hinting.

And though I do NOT understand the subtleties of hinting (I just click F7) putting nodes at extremes has broadly become the way I draw most curves anyway.

When my glyph has a broad curves at the extremes or corners that turn at the extremes, everything is honky dory...

But things don't always work out that way:

When I put nodes at the extremes of tiny curves (like in A,V and W glyphs with diagonals that have rounded edges) the curve gets wobbly.

Do I need to turn my UPM up to 2000 to handle the fidelity for these fine curves?

Or can I just not worry about it and let my nodes just be really close to the extremes in those few cases?

I DO plan to generate both OT type 1 and Truetype eventually...
