Decent growth rate ?

My young male BP,s weights have been as follows. All weights were taken after he has took a poop.
4/8/15..........225g
5/3/15..........262g
5/25/15........291g
He's eating good, looks nice and plump and to me has visably grown pretty decent since I've had him.

They all grow at different rates. Also depends on feeding frequency. As long as they are eating and not losing weight, they're ok.
