I have no idea.
According to this article by Tim Henriques:
A "decent" level of strength is defined as:
Decent is another way of saying "not bad." I define a decent level of strength as meaning that the person probably works out to achieve that level of strength, but some naturally stronger people will be able to achieve that level with no training. A person is strong enough so that their strength doesn't limit them in their everyday life.
Decent wouldn't be considered "strong" in hardly any strength training circles. I believe that almost all people can achieve the decent level of strength through training. My guess is that most people would achieve this level after 6-12 months of training. Some would achieve it earlier, and it might take a select few several years or more to achieve.
The decent level of strength is a good milestone to shoot for as a beginner. I'd also classify failure to lift 50% of the decent level of strength as being weak in that exercise.
He then goes on to list a "decent" bench press for a man as 225 or 1.25xBodyWeight
