I wonder why you don't use the warm-up to analyze your opponents? Personally, I do just that to understand which of them is the most dangerous and shoots more accurately. But it's your choice, so check out how to skip warmup in CS2 on VRedux. I tried this method when I suddenly had to leave, but the match had already started, so every minute counted. But don't forget that this only works if you are on a private server; in real matches, it's better to buy a private cheat for this. By the way, you can do this on VRedux too.
