I recently re-installed and started a game Civ4:Col after a hiatus of several years. I had eagerly bought the game when it first came out, but after a handful of frustrating games, I lost interest in Col and went back to BtS. Then, a couple weeks ago, I decided to give the game another chance inspired perhaps by a biography of George Washington I was reading at the time.
This is the first time I have played with patch 1.01f. Many people, both in this forum and elsewhere, say good things about it. Its readme has this very intriguing line:
The Royal Expeditionary force increases less rapidly as the game progresses, depending on difficulty level.
I wondered how this change affects the things Axxon talks about. At first, I was going to ask if anyone had looked into it yet; but then I decided to see if I could figure it out myself and I think I have. Before I start, I should say that I am not entirely proficient at reading code, but I think I understand it well enough to figure out this question. If someone else wants to have a look and either confirm or refute my findings, then I would welcome it. With that disclaimer aside, here's what I found.
The REF is all about bells - and for this it's the amount of bells accumulated in all your cities that counts. After 75 bells the King will increase the REF, ...
The threshold for the initial increase is now scaled to both speed and difficulty; at Normal Speed and Explorer Difficulty, it is still 75 bells for the initial increase. I don't know if it was scaled previously (and I didn't save copies of the old XMLs before I applied the patch, so I can't check.)
... , reset the bell "counter", and the next REF increase will require 10% more bells. ...
More significantly, when the "bell counter" is reset, the next increase
now requires 25% more bells, not 10%, so REF increases will be less frequent. Either with or without the patch, the first increase comes at 75 bells (Explorer, Normal speed). Originally, the second increase came at 82, third at 90, fourth at 99. After 1.10f, the second increase comes at 93, third at 117, fourth at 146.
Note that the percentage increase is applied each time to the "new" threshold, not to the original value of 75; therefore the series (rounded down) is 75, then 75 x 125% = 93, then 93 x 125% = 117, etc.
... There's a bit of a twist though, in that the next REF increase will also add 10% more units to the REF. The game always rounds down AFAIK, so you won't get 1.1 units added.
This is also scaled to the Difficulty setting, and it has been reduced for all levels
except Revolutionary. (Again, I don't know if this was scaled before the patch.) Instead of a flat rate-of-increase of 10%,
this factor now ranges from 2% at Pilgrim to 11% at Revolutionary. This means a reduction in the rate at which the game increases the number of new units that are added each time; therefore later REF increases will be smaller in size (
except at Revolutionary, where they are slightly larger.)
Conclusion: with the patch, the REF increases occur less frequently, and those later in the game are smaller in size. Hopefully this reduces the significant pre-patch disincentives to early production of bells.

There was also this interesting tidbit in the changelog for 1.01f:
Satisfying the King's demands delays increasing his expeditionary force.
It appears that
for every 50g you agree to hand over to that greedy bastard on the throne, the "threshold multiplier" is increased by 1%. (This value is the 25% "more bells" formerly 10% that we talked about earlier). For example, say you make a 200g "donation" to the king. This triggers a 4% increase in the threshold multiplier, which starts at 25; 25 x 104% = 26; therefore, it will now require 26% more bells to trigger the next REF increase, instead of only 25% more. It's confusing since you are actually changing the rate-of-change; but basically, that 200g "donation" means an additional 7 or 8 bells you can generate before the REF will increase again. Note that these "donations" do not include taxes; it only counts if he comes to you directly demanding money, and you decide to pucker up.
