So I enabled logging. It's slightly annoying when you run many and multiple games since they share logfile and there is no real distinction between them except civname and turn numbers.
Anyhow. Restart. Random stuff. Deity. Epic speed. Normal sized map. 8 civs 16 city-states etc. The normal stuff. First 100 turns (+- a turn). For convenience I have summarized the DifficultyHandcapLog.csv by player and event.
It might be a matter of opinion and wording here but it's a fairly substantial amount of bonuses being dished out if you add the numbers up. But then how much is to much or enough is hard to say, it's like how long is a string. Who knows.
Settling the Capital, 73 gold, gap, food and production. The gold might not matter all to much at the start, but it shortens the time it takes to buy a unit or make a downpayment for some nice building in your new shiny capital. 73 gap is 12% on the way to the first golden age assuming they cost 600 for the AI -- I forgot to check if they get some bonus there to. 73 food guarantee that you'll have pop growth for the next two or three turns. 73 production should complete either the shrine or the monument or a free scout, second warrior or possibly even a worker.
Getting 73 free food is like every AI civ being Spain, if you are Spain you get a large double dip here. Some other civs will do better then others for sure.
Settling a city. 73 gold, gap, food, prod, cult and science. So it's even better then getting your capital on.
Building a wonder and Generating a great person is 73 gold and gap.
Era change. 219 gold, gap, food, prod, cult and science. This is as noted 3 times the normal yield here for everything.
T74 The most sophisticated culture already has 4 policies, everyone else have 3, I only have two but then I went shrines before monuments as I started as Spain and wanted to try the new "Goddess of the Home". It might not have been the optimal choice but I didn't know about my competition really. I didn't, or plan to in the future, log-cheat.
T88 First era change (Netherlands). With some level production bonuses etc that 219 production should be a free settler, or an ancient wonder or a few buildings and/or units. It should be a free tech to, or a serious discount on one.
Triggers, Name, Gold, GAP, Food, Prod, Cult, Science
9 Siam 803, 803, 584, 584, 511, 511
6 Poland 584 584 584 584 511 511

1 France 73 73 73 73 0 0
Siam already has 2 wonders (T41-Stonehenge and T72-Mausoleum), I have 1 (Pyramids, first wonder of the world), India has 1 (T78-Temple) and then the Celts got one (T68-Statue of Zeus).
Siam should already be in a golden age since the first one is just 600 points (for a player, possibly even less for the AI, I didn't check the full list). Poland, Netherlands, Maya and the Celts might be there if they got some GAP from another source. If not there yet they should be there soon.
As noted above Siam already triggered 9 handicap events (or 8 if we don't want to count the capital).

And so far Siam has as noted gotten 803 free gold and gap, 584 bonus food and production, 511 free culture and science. Not bad. Poland, Netherlands and Maya are on the same level at the moment, Celts slightly behind but about to cash in to Siam like levels. I guess France and India will get there eventually. I would love a big army and just crunch them now while I can but I sadly picked differently while playing and didn't know the result until after turn 100 when I checked the logs.
Two world religions are already founded. Siam (given considering they got Stonehenge) and the Celts.
India and France have been having superbad times, they are my neighbors. They have been ravaged by barbarians and have not even managed a second city yet. I have not even screwed with them, yet. India gave up and built a wonder and I'm not sure what France is really doing until I watch the log but I'm guess building units desperately.
I don't know about the other civs in game yet since I have not found them, the map is a bit weird and there was to many barbarians about so I have not had a proper world scout as of yet. But I know how it looks around India and France. I could take the other things from logs. Netherlands, Poland and Siam are about to finish the first policy tree (they all went tradition). So I'm already two policies behind them. According to the logs they are all at 10 or 11 techs already and researching the first tech after their era changes in 8 turns instead of the normal 20+ turns.
India, 10 techs, 4 tradition, 9 pops, 1 city, 1 wonder.
France, 9 techs, 3 authority, 3 pops, 1 city, 0 wonders.
Spain (me), 9 techs, 3 progress, 17 pops, 4 cities, 1 wonder.
France recently built a settler but I have not seen it yet. Barbarians might have eaten it. India has not yet finished one. India built a trader they are sending to me instead.
I think we have very different ideas about what is insignificant or minor bonuses entail. I'm not really seeing the smart plays. I'm seeing the bonus rain fall over them. Which may or may not be what they need but what they get are not minor or insignificant amounts in my opinion.
I'll bet at least a gold that Siam will snowball hard in this game.
