I'm curious.
Even after I get Mineral Miner III's, I prefer to continue building Mineral Miner II's because they finish building in a single turn. Thus, I get the added production immediately instead of getting just 100 more per turn two turns later. Later, after I've maxed out my facilities, I'll upgrade them all en masse. It doesn't seem that I lose any production while I'm upgrading.
Does anyone else keep building Miner II's after they've researched Miner III's?
Because I do things this way, I really hate it when I tell it to 'Upgrade Facilities', and it changes all my Miner II's in production to Miner III's. The same goes for farms and research labs.
Edit->
Hmm... I really, really wonder now. It *always* seemed I was getting a better deal by building 25 Miner II's and then spending 25 turns probably upgrading them all to Miner III's. It just didn't seem worth it to wait an extra turn for each facility just for 100 more minerals per turn. But if it turns out that I'm spending 2000 resources per turn for 25 turns to upgrade it to a Miner III, then maybe I'm not coming out ahead after all.
Where is mathematically minded Zanthis?
