For regular videos, upload time can be important because subscriber notifications are crucial. But shorts are different.
Just because I upload it now doesn't mean it spreads immediately.
Shorts are when the algorithm tests the waters and then suddenly explodes a few hours or days later.
Whether you upload it at 10 AM or 10 PM, a video that is going to explode will eventually explode.
It is always more advantageous to upload frequently regardless of the time than to upload one a week just to meet a schedule.
Uploading once a week: Like buying one lottery ticket and waiting to win.
Uploading 4-5 times a week: Like buying multiple lottery tickets every day with high odds of winning.
With Shorts, the algorithm only understands your channel's data and starts pushing videos to the right target audience once a 'quantity' accumulates.
