Should I keep a close eye on this?

[B.O.S Reptiles]

200g-300g BPs I feed weaned rats @ around 40g.
400g-1500g BPs I feed small rats @ around 80g

EDIT: 500g for a 5 month old BP is very rare.

Thanks!! I'll keep this feeding chart in mind. So should I keep an eye on these guys, or just continue our routine, and not stress about this?
