Film exposed at the beginning of the cartridge?

When I put the cartridge in, since there's already a little lenght of film that is visible at the beginning of the reel and that therefore, that part of the film might be exposed... Should I shoot for a few seconds before actually filming what I have to film (to make sure it comes out the way I want it to)?
If so, how many seconds approximately?

Running the Super 8mm cartrige for a couple seconds first is a good idea. The light stuck film, only goes
back into the cartridge barely an inch either way if that much. The cartridge was designed for camera loading
in full daylight without fogging the film. However, the first few inches of film have a backward twist to it
owing to the film path in the cartridge, so it can take about a full second or two to run completely steady. Those first few inches though are great to shoot a color chart, gray scale, or film slate, or do a focus check. This steadiness would also apply to
a given cartridge if it has sat for an extended period of time prior to filming on it again, due to the torturous film path.

In general it has long been recommended to idle transport the film enough length such that the film which was in the sharp bend in the cartridge. I.e. half the height and the depth to the rear, some 15 centimeters. When the film had been left standing still long enough the film would adopt a strong curve/bump around the sharp bend and go out off focus when this bump would be exposed at the gate position.
