Here's a list of files 20kB (rounded) and over that were on the original CHM site. Just for 'fun'.

Aah yes, the in-development USACA system. Very dense visible points and shaping points, combined with a very long route, led to CA1 topping off the list. It's what CA89 and CA20 suffer from as well.
> ca.us101 - 41kB / 804.7mi
A long route with dense interchanges on freeway segments. There are a few shaing points and a couple visible points that could be removed, but overall, not bad.
> ab.ab002 - 30kB / 807.3mi
My draft file for the CANAB system is down to 19.2 KB.
446 waypoints: 220 visible, 226 hidden. -> 295 waypoints: 258 visible, 37 hidden.
Average spacing: 1.81 mi -> 2.73 mi
Average visible spacing: 3.69 mi -> Average visible spacing: 3.12 mi
> ca.i005 - 29kB / 806.5mi
A very long freeway with densely spaced interchanges in places. Shaping points are well done; minimal.
> or.us030 - 29kB / 477.9mi
Many of the shaping points, particularly along I-84, can be cut out.
I cut it down to 18.4 K.422 waypoints: 219 visible, 203 hidden. -> 276 waypoints: 218 visible, 58 hidden.
Average spacing: 1.14 mi -> 1.73 mi
Average visible spacing: 2.19 mi -> Average visible spacing: 2.19 mi
I actually added a few shaping points (10?) in the eastern part of the state on I-84.
> bc.bc003 - 28kB / 518.5mi
A cursory look shows a lot of shaping points could be cut out. Visible ones as well.

> ky.ky0080 - 22kB / 476.1mi
Heh. Tons of state routes here. KY needs 4 digits to number `em all.
> on.tchlak - 26kB / 1030.5mi
A long route that's about where it needs to be WRT shaping.
> ca.ca099 - 24kB / 434.8mi
Not as bad as CA1, 20 or 89. Another case of a long mostly-freeway with dense interchamge spacing tying our hands. Although, many of the shaping points could be eliminated. Also looks like there's opportunity to snip out some visible ones on the surface road, such as in the Yuba City area.
> me.us001 - 23kB / 524.8mi
This has always been rather dense on the visible waypoints. I've trimmed down my local copy: 17.6 K / 524.05 mi
347 waypoints: 310 visible, 37 hidden. -> 272 waypoints: 240 visible, 32 hidden.
Average spacing: 1.52 mi -> 1.93 mi
Average visible spacing: 1.70 mi -> Average visible spacing: 2.19 mi
> mb.mb010 - 20kB / 508.5mi
My draft file for the CANMB system is down to 11.2 KB.
285 waypoints: 93 visible, 192 hidden. -> 172 waypoints: 115 visible, 57 hidden.
Average spacing: 1.79 mi -> 2.94 mi
Average visible spacing: 5.53 mi -> Average visible spacing: 4.41 mi
