Advice on feeding amount

[JraX]

Hi, hoping someone can help as I’m so confused, I’m just not sure if I’m over/under feeding my pup. she’s a little cavapoo, 12 weeks old weighing 1.6kg. she is on wainwrights superfood salmon which states it has 407cal per 100g. I’m currently feeding 70-80g a day split between 4 meals. any advice would be appreciated many thanks

Is it this feeding guide? I hate guides that go by expected adult weight rather than current puppy weight. I'd have over fed my puppy, as I expected her to reach 12kg and she's barely made 9 kg.
Do you know how much an adult cavapoo is expected to weigh?
