You may see more males that you feel are smaller than you think they should be. They don't take as long and don't need the weight that females need for breeding, so they are fed enough to be healthy but not chubby. Many don't want fat male breeders either as they can sometimes be lazy breeders.
Using the rule of thumb I read in this thread earlier (100g per month) the the average 2yr old bp would be about 2400g. At 3yrs it would be at about 3600g. That's bigger than the biggest female that most of the members here have. Once they get to a certain weight they sometimes level off for a bit and then you may see a growth spurt. Raising several snakes from hatchling to one year old is nice, but they don't always continue to grow at the same rates they did earlier in life.
