I completely brain farted and thought this had a Nov 16 deadline, oh well. I had a t271 SV that I COMPLETELY screwed up my math on; I was literally waiting on bulbs and sitting on 5k more cash than I needed to buy all the parts, and somehow did the math so wrong that I would up with 2 scientists extra when I finally bulbed off to finish the tech tree. I reloaded back to find out when I was supposed to bulb off all my GS, and had a 265 win, so I had 6(!) turns of completely wasted waiting.
Other than that, I went completely peaceful, 5 city tradition, with the standard rati/freedom/commerce finish. I think I could have shaved off at least 10 turns by founding a 6th city after NC/HG, or maybe by trying to take Ghandi's cities after I got the Foreign Legion. I also ate several large poop sandwiches by getting beat 2-4 turns short of Oracle, Porcelain Tower, and Cristo. Losing PT and Cristo was totally my fault, though; I could have finished them before I did but thought I was far enough ahead to finish other buildings first. I also screwed up my Rati finisher timing and had to use it on Nuclear Fission instead of Nanotech, which probably cost me another 3-4 turns. I probably could have bulbed to Rockets a little sooner too, and saved a turn or two by finishing Apollo earlier.
One final thing, I noticed in my reload that there seems to be a nasty bug where you can lose most of your science overflow after bulbing a lot of GS's. Has anyone else run into this and know what causes it / how to avoid it? I have a save demonstrating it here, if you don't know what I am talking about:
https://drive.google.com/file/d/0B_h-nvJMOUvaRFhVeEExMHJTclE/view?usp=sharing
The save is right after I bulb off 8 scientists, and I have 35694 bulbs of the 12100 needed for Nanotech. After hitting "Next turn", I discover Nanotech, and only have 8800 bulbs of progress towards the next tech, Telecom. It can't be coincidence that 8800 was the exact price of Computers when I bulbed it, and after that when I bulbed Robotics, it did not give me the tech right away, despite having way more bulbs than needed (even before using the GS). I also did not immediately get Nanotech after I bulbed it, again when I had more tech than required even prior to using the GS. My feeling is the bug is somehow tied to those times you bulb a GS which _should_ immediately discover the tech (i.e it completely fills your progress bar), but instead it just gives you a bunch of overflow bulbs and no discovery.
