[R-meta] (Too) Many effect sizes for one single group

Dear Wolfgang,

I hope you had a lovely start to the year.
I am sorry for starting the year with questions, but I just wanted to check
whether there is any drawback from including a lot of effect sizes from a
single paper when most labs contributed to the meta-analysis with just one
or two effect sizes? This resulted in a dataset where half of the effect
sizes come from multiple experiments run by the same group. The nested
nature of the data and dependency of some effect sizes coming from the same
participants is acknowledged in the model.

Thank you!

Catia
