Ractrot came up with the idea of using a sniper rifle, that you buy during shakedown, same time as grenades, to snipe the first collectors from extreme distance. Then he made the idea even better. When you start CtC, do NOT move, just crouch, zoom in to the max, and aim at this spot: https://imgur.com/h9h5X4k Look at the spot where the sniper aiming reticule circle intersects the horizontal line on the left side. Spam shoot at this spot (keep aiming, double tap F1 between shots) until the collector marker disappears from the map, proceed normally. My best attempt so far was 5s faster than this video by MH:

You can end up on a slightly different position than the one in the screenshot, because the amount of ticks you move isn't consistent. The trick isn't pixel perfect though.

If, for whatever reason, found yourself here searching for another CtC snipe reference, you've come to the right place!

Match the images above (either or), scope out, scope in, and fire! If the reticle can't land in the center of the window, it's best to aim to the left. Zooming in after scoping out isn't required. Vertical lineup does not matter at all since it'll be fixed once you scope out.

Be mindful that the sniper does have bullet travel and playing replays too quickly can cancel shots.
