That would be the best possible news ever. I don't know if it's possible / probable, but that is a fantastic idea. To my knowledge, there has not been any trials with 4g of EPA. So why not use RI to test for as many SEs as possible? This could be a reason why it wasn't stopped at 1st interim - if DES or anything else the was added recently, was not measured from the beginning, so why not measure from that point until 100%?
