First draft of prospective resource placement rules and frequency for Hardwood:
Hardwood is valid in: grassland/plains forest/jungle hills/flat
Hardwood is placed around production-poor starts in non-tundra forest or jungle. Another resource is chosen if the tile does not have jungle/forest already
After starts are finalized, bonus resources are placed on random tiles NOT within 3 tiles of civ/CS starts. Hardwood is placed based on the frequencies listed below.
Hardwood is not placed if feature is not jungle/forest already (unlike deer, which will place forest under itself after the resource is placed on the map).
precise current numbers (expressed as frequency of resource placement):
deer:
1/6 tundra forest (flat or hill)
1/8 featureless tundra (converted to forest)
1/25 non-tundra forest (flat or hill)
1/15 jungle (flat or hill)
banana:
1/15 flat jungle
1/20 tropical marsh
proposed numbers:
deer:
1/6 tundra forest (flat or hill)
1/8 featureless tundra (converted to forest)
1/25 non-tundra forest
1/25 jungle hill
banana:
1/20 flat jungle
1/20 tropical marsh
hardwood:
1/20 non-tundra forest,
1/25 flat jungle
1/15 jungle hill

I need to consult on these numbers still, but posting it now so it doesn't get lost. Adding a 2nd resource to forest allows us to bring forest frequencies up.
Not sure what the desired level is for these, but roughly 1 bonus resource per 10 valid tiles seemed like a decent starting point.
Keep in mind that, because hardwood's improvement is so delayed, the aim of this is to slightly increase resource density so that hardwood near your start does not hobble your early economy.
I'm not sure why flat jungle frequencies are so high, while forest resource frequencies are so low. I feel like I am missing pertinent information on these, but for now, this would regularize placements of resources until someone can tell me why these are so uneven right now, and why levelling them is wrong/unadvisable.
