hopefully we can already calculate the % as soon as we see villain's hand(s).
I tend to look towards the next table I'm needing to make a decision on... I don't typically watch the 'all-ins' play out. I will often take a quick look to see what villain got it in with in that particular spot & might pull up their player notes & make a note for future reference ('it depends' what tables I'm playing on and if villain's play is worth noting (played outside of norm, or was shown to be capable of something, etc. etc)
tldr - look away from screen
