Hi there!
This is mainly a personal preference. I feel like it's more of a challenge when you need to scale up the production of science packs rather than creating a large lab farm.
I'll keep this in mind for Factorio 0.15, I likely have to revise the mod then and I might rebalance research times and item count.
I'm kinda hoping they'll make research in the base game far slower, or at least make it so that you'll have to choose one thing over another; For example if you invest in train research then you can't get bots as quickly, and vice versa. Maybe even a "marathon" setting for the game, would like to see a mod like this becoming redundant.
