34 is possible on Green Hill 3. There were several times I nearly got it, but messed up the capsule jump. That's the thing that prevented me from getting 34/35. You can do the boss battle better than you do in your video, and you can shave off time at 0:21-23 in game time. Rather than jumping up that little hill, if you stay rolling, you'll roll on top of the enemy and then you'll go back to full pace. If you do all that, you can get at the spring right at the beginning of 0:28, and then if you get the capsule jump (this is where I failed), you can get 34 (and 3/4ish)
