I re-ran the Vorbis tests again, this time at -q2. Tested effect of ICCpatch on lvqcl's compile and changed to last Blacksword compile (1 whole week newer). I was also curious to test LAME compiles from Rarewares with ICCpatch. Here's the results:
using test WAV 16bit, 48KHz, 2ch, 1,025,507,372 bytes
encoder & version (all run at -q2) time rate filesize
