4482MB comes too close to maxing out the capacity of a 4.7GB blank, 4700000000/1048576=4482.269287. No compression program is perfect; the output may be a little under or over the target value of 4482. If it’s under you might be ok but if it comes out over you’re SOL.
I set the target to 4472 to allow a bit of overage and have never had a problem. I assure you’ll never detect a Ø.23% difference in compression.

I agree 100% and if members want to make a custom size of 4482 and expect perfect burns, then send me a invitation to the party, because you will have plenty of coasters.
