Yep, that my opinion. I hope you vary his feeers too. Make sure you gut load them well. Once he's a year then I would definitely do feeding every other day or just a couple everyday.
The guidelines are made as a general rule of thumb, something to follow but you have to learn to read your chameleon. They are all different, if your Cham is eating well, it's a good sign of health, just try to regulate it to avoid future issues.
Imagine he's eating all that and then you cut his food in half once he's a year, that would be a little rude, he'll be fine.
