I would say it's possible. Are you saying your current max is 255? If so, I would say it's likely you'll see a dramatic jump in your 1rm. You're in a phase of lifting that you'll just see faster progression a lot more. Once you get to 315, you can't expect the same progression. Once you get to +405, that's typically when you start being very pleased with just 10lb increases.
With all that said, smolov was the most rewarding program I've ever ran for bench... But, it was also the most non sustainable program I ever ran. Most people do some sort of modification to it to make it work for them.. that's likely how the Jr version came into existence.
