|Drew,
|
|I sure do hope you report back on what you find, & your final
|resolution.
|It's been an interesting thread. Academic for us, painful for you.
|
|When you do the <i> vs <n/2+i> extraction test, you might want to
|compare it to
|a loop-remove method, too. On UV, sequential <i> extractions are about
|as fast as loop-remove when attribute marks are the only system
|delimiter used.
