Is there an animation frame with a programmed stroke of 25 frames per second

Question

Should I use a request animation frame if I force it to continue 25 FPS. This is why I ask:

Normal RAF behavior: a1000ms / 60 fps = 16.66a This is the standard refresh rate for most monitors.

Removing FPS up to 30:

1000 / 30 = 33.33 , which is exactly half of 60, and this means that any other RAF execution will do something logical and consistent

Reduced FPS to 25:

1000 / 25 = 40 this is not divided by 16.66 (normal RAF time for updating the screen)

With this logic, I will have to draw something on the screen every 40 ms, but this is not possible, because one frame is 16.66.

I lower the number of frames by standard:

 fps = 25, renderRate = 1000 / fps, function animation(timestamp) { draw.requestAnimationFrame = requestAnimationFrame(animation); now = timestamp; elapsed = now - then; if (elapsed > renderRate) { then = now - (elapsed % renderRate); //Some code for execution goes here } }
