In fact, if 37.1 is indeed the final PR, I can confirm that the cheapest way to reach it is 7444344 which costs 248 gold.

After sorting for upgrade efficiency (PR gain per gold) and applying them in order, without engine6 you get to 37 exactly. Engine6 is the cheapest of the remaining updates, so you have to include it. Engine6 brings you to 38.7, with 1.6 PR to spare. There is no upgrade pair that you can remove and stay at or above 37.1, so you get to remove the most expensive single upgrade, which is body5.

So, if anybody has a screenshot that proves 37.1, that's the way to go.
