I've been having a look at the comparison of the top 5 teams, made by Leif Erikson in the XTeam thread, and plotting our own progress against them.
For what it's worth, these were my thougts:
Start
One Short Straw, Xteam and CRC settled on turn 0.
Murky Waters and Smurkz settled on turn 1.
On turn 2, we were the last to settle.
However the starting location might have been more significant.
Well, not really, apart from the luck of missing the unseen copper. We all settled on adjacent tiles.

We all made sure we got the eastern gold and left the western gold for later. The only slight surprise was Smurkz leaving the cattle to another city. The rest all included it in London's borders.
Research order
OSS, Smurkz and CRC went for Agriculture first - as did we.
Murky and Xteam went directly for Bronze Working.
Murky went BW=>Agri=>AH=>Wheel=>Mysti
OSS went Agri=>AH=>BW=>Wheel=>Pottery
XTeam went BW=>Agri=>AH=>Wheel=>IW
Smurkz went Agri=>BW=>IW=>Hunting=>AH
CRC went Agri=>AH=>BW=>Writing=>Mysti
We went Agri=>AH=>Hunting=>Archery=>BW
So there is a clear difference - we were the only ones to go for Archery in the first 5 techs.
We were also the last to get BW. We got there on turn 59.
(Murky on turn 21, OSS T42, XTeam T19, Smurkz T35, CRC T42)
Getting it hooked up showed even more extreme differences - but again I would put that down to bad luck.
Foreign Relations
We all met Mansa, Hannibal and Alex early on.
We knew them all by turn 30.
(Murky turn 20, OSS turn 14, Xteam turn 38, Smurkz turn 14, CRC turn 44)
Some attacked them in the very early stages.
Murky had taken Timbuktu by turn 48 !! The benefit of researching BW first, finding copper in London's borders, detecting Mansa's land by turn 30 and hooking the copper at the same time!
XTeam took Timbuktu on turn 56. They also researched BW first, hooked up their copper on turn 31, produced their first axe on turn 38. Went to visit Mansa, and would surely have taken it earlier but for a bear attack on their axe which necessitated 4 turns healing!
But not everyone went for that early a rush.
CRC went for Alex first, taking him out between turns 130 and 159.
Smurkz too went for Alex, and his cities died between turns 99 and 159.
OSS were pretty early in their demolition of Hannibal. He only had 2 cities when they came visiting on turns 80 and 86!
However, of course, that's where we deviate completely from the top teams. We didn't feel powerful enough to attack any city until turn 141, when Corinth went. Then nothing until 157 when we took Kumbi. Notice we were also attacking cities within range at this stage, rather than feeling able to take out an opponent.
We didn't really start cutting down the opposition until after turn 200 - and then of course they were quite powerful themselves.
Overall
I think we were unlucky, but we were also unadventurous.
Had we gone for BW earlier, and possibly missed out archery, we might have found ourselves initially frustrated at the copper being out of reach of London's borders, but we would have been an attacking force much earlier.
We should have ventured out and found the AI civ's borders sooner.
The other teams were having discussions about how to quell 3 opponents in AW - they were more confident knowing they were in a strong military position - we discussed defence, and a more limited expansion by taking small bites out of the enemies.
