Decided to figure out the new way to upgrade marines efficiently, since the cost of marine minor upgrades was changed from 400/600 to 500/700. I define efficiency in this case to be the lowest total cost per unit of DPS, aka "unit price".
The first set, called "upgrade list 1", is straight damage upgrades.
The second set, called "upgrade list 2", is stim + minors (stopping power and stim addict/combat shield) + rapidfire.
The last set, simply called "upgrade", is the optimal upgrade path - created by comparing the unit prices of the next upgrade in each upgrade list, and choosing the one which gave a lower unit price. The "comparison" column shows the alternative (higher) unit price.

Direct link to image in case it's not visible on TMANote that if you're going straight marines from the start, it makes more sense to open with stim instead of +1 because you start with 500 minerals anyway (and stim gives more DPS).
