Clock-wise, this is easily the longest section of the stage.  Skip the shielded enemies at the start, and head to the center of the next room to get all four enemies to drop.  Dispose of them quickly to open the door.  Kill the Hornet, then before you get on the platform, hover a bit past and to the right of it, holding B to lock on.  You should pick up at least one lock-on here; release B then hover back to the platform and ride it up.

There are two Chaos enemies that need destroying to unlock the next door.  There are a variety of ways to dispose of them: lock on to both then run behind them and shoot once they get out of hiding (slow), let them attack you and shoot them while they're attacking (fast but requires you take a hit), or even get up close to one of them, punch to hit through the shell, and create an explosion that takes out the other one in the process (fast, but very rare).  Get rid of them in some way, then go through the door and jump down.

The lock-ons you made before hovering to the rising platform earlier on should, ideally, have taken out the two enemies down here through a wall, opening the door immediately.  If there's still an enemy alive, you'll have to destroy it to open the door, wasting time.  Continue forward through the curved hall, and jump and hit the switch above the lasers as soon as you can, then pass through now that the lasers are gone, take out the hiding Chaos, and hit the next switch to keep time stopped.

In the acid room, hover forward, using the blocks or even the short walls that denote where blocks will pass through in order to advance.  After the drop, you'll want to continue to the vertical-path blocks.  Remember that the outer ones move up and the center one moves down.  See if the outer block isn't so high that you can't hover onto it, but isn't so low that it wastes time for it to move up to the next door.  Let time restart, then ride it up to the next door.

This curved hallway plays a lot like the one in Tails' section.  Stop the clock once, then when you're a good deal past it, turn around and shoot the switch again.  Go through the door, and don't hit the checkpoint or else you'll lose time if you die in the remaining part of this section.  The clock should be stopped as you start the long fall, and start up when you're partway down.  When the clock starts, the lasers reappear, so take care to avoid them as you fall at full speed.  At the bottom, there are three time stop switches on the wall.  Either lock onto one of them, or just fall through and have Eggman's machine knock the switch well out of place, then continue forward.  Defeat the two hiding Chaos enemies, then continue to the next room and try to hit the switch to keep time stopped before it can restart.

When you're on the block, jump and hover backwards while holding B.  Lock onto the switch (don't shoot yet), then turn around and hover back onto the block you came from.  Time will restart, and once it reaches the "magic number" you remembered (30.1 seconds plus start time), that's your cue to release the shot.  Time will stop right as the block gets to the level of the door, so hover over and get through the door, then hit the next switch.

 

Get to the second time stop switch in the curved hallway, shoot it, let the door open, shoot it again, and lock onto it once more but don't release yet.  Go through the door, and don't hit the checkpoint or else you'll lose time if you die in the remaining part of this section.  Head through the next door when it opens as well, and once you're on the balcony, release your lock-on.  If done correctly, this shot is sufficient to keep time stopped through to the next time stop switch, enabling you to play the rest of the stage on a frozen timer.

 

Fall through this long shaft without bumping into any enemies, and at the bottom, there are three time stop switches on the wall.  Fall through one of them and have Eggman's machine knock it well out of place, then immediately hover and turn to lock onto another (again, don't release), then continue forward and down.  Release the lockon, defeat the two hiding Chaos enemies, then continue to the next room and try to hit the switch to keep time stopped before it can restart.

The last room can end up taking quite a bit of real time, but no game time.  Make your way to a raised floor on the side.  Jump, and at the peak of the jump fire a volkan cannon shot.  You may see it crash into the wall; this is no good.  You want it to hover just above the higher floor, and hit the door for a hit.  Throw in a shot at the time stop switch every so often so the clock doesn't start running again, and keep trying shots at the door until you hit 12 of them to advance.

Dive down into the Kool-Aid, holding left and slightly down, and aim for the time stop switch atop pillar #4.  Don't resurface; you're going to take a different path that laughs at everything you normally have to do in this section, and that leaves the "normal" path in the dust.  Head forward--not into the lasered-off entrance, but to the entrance below it (the one that Rouge went through).  Dive down to the time stop switch just below the moving-block path.  You don't actually need to hit the switch, but it saves time.  Shoot back up with A, and move into the right corner at the top of the room.  It's covered in acid, so you'll take a hit, but that's okay.  After being hit, move back to the same corner and press A to shoot up through the ceiling!

Now you're gliding around (not swimming) out of bounds.  Glide forward, and eventually, next to a room full of lasers, you'll see a cubical room.  Aim for the right side of that room, and enter the wall to go back in bounds and back to being considered as swimming.  This is the room that holds the final security door switch, so swim over to the switch and press it.

Kill both enemies up on the ledge to open the door, then make an easy run to the Chao.
