I love the commenting competitions but when I did the beast at whaleshares it was too much and I burned out afterwards.  What was it 50 comments a day?  Ahh it was nuts. But 10 a day is reasonable.  I suggest we comment on 50% more posts than we would ideally receive comments on our own posts.  So if I hope to get 10 comments on my posts I’ll comment on 15 posts.  Obviously it doesn’t always work like this and not everything is reciprocal but if we can engage more there is more engagement to go around !
