    Ok, pretty easy to do with 3rd release, and perhaps not so easy with 4th release in my case since the table is pretty squished together in my effort to make it more responsive. I did lower 4-3 a little, but as it currently stands there's no room to lower 4th release without going below 4-3. I've loaded the modified numbers into my PCM and am going for a test drive.
