Blue screen is definitely a good thing, because it’s THE ONLY interaction with your opponent during the match, and I feel like without it we could as well play alone.
But if we are already talking about the blue screen I think that it needs a little fix to actually work as intended, if it’s even possible, because I have no idea about technical details, I had few problems with that on last competition in Sweden, and then I realised that I actually had similar problems, but in other direction, while playing at home:
Sometimes (or probably always, but usually it’s a little delay) there is a delay between competitors, one player is starting few seconds later, time for him is normal, but blue screen still occurs when the 1st player is finishing in real time, sometimes lying to the opponent a lot.
1st case was when I was playing numbers against Sylle Arvidieu, and I saw blue screen after 10 seconds of memorisation, so I went for 60 with big “what just happened” in my head, then it turned out he finished in 26 seconds, and people watching the match told me that my attempt started 15 seconds after his attempt. We had a rematch there.
2nd problem occured when I was playing cards with him. I saw blue screen a second before finishing my attempt, so if it would be numbers, then I would once again go for 60 which would change my score a lot. After the attempt it turned out that I was almost second faster than him actually, and I still saw a blue screen. Audience told me that for them I also finished 2nd. If I would go for 60 then we would never know that blue screen was actually lying to me and I would lose by time because of that, even if originally I was faster, because I just had a ~2 seconds delay. I lost it anyway, because of worse accuracy (where I can also argue accuracy could be worse because of lesser motivation after seeing blue screen that shouldn’t be there), but I think you get my point here.
It definitely wasn’t a problem with my internet connection, because I am using this mobile internet everytime I am not at home to play games where even a little higher ping would be very noticable and I never had problems with it for years, so I don’t believe it’s the reason. I would like to know if there is a chance to actually remove this kind of problems, because if it can happen, and if it’s a real issue, probably happening more often in small degree (like sometimes you CAN’T see blue screen even if your opponent finished a second faster than you, because on his screen he is still on the attempt, and that’s the thing I had much more often while playing online, where I didn’t see blue screen but I was still significantly slower than my opponent, so I should be able to know that, but I didn’t), then blue screen is actually pointless, because it doesn’t show you the truth and instead of that it can mess with you a lot.
If delay between me and Sylle would be 5 seconds instead of 15 in our numbers attempt, then I would finish in 22 (my average time that I was going for), Sylle Arvidieu would finish in 26 like he did, and he would NEVER see a blue screen, which would be also lying to him, because then he would probably go for 60.
So there are issues. Without them: I believe blue screen should be there. But if we can’t realistically remove this kind of problems on real competitions then it would be probably better to remove it to don’t mess with competitors’ scores because of some technical issues.
