Analyzing VAR and GLT strategies

I’m thinking about the distinctions between goal-line technology (GLT) and VAR, especially with semi-automated offside technology (SAOT) used in various competitions. Maguire suggests limiting VAR to objective decisions, which could reduce stoppages and maintain objectivity while possibly accepting more "clear errors" in subjective calls like fouls. There are pros and cons, including inconsistencies with handballs and penalties. It might be good to discuss impacts on competitions and fan sentiments about time delays and celebrations. What does the user want to focus on?

这是个“只保留客观技术、缩减主观判罚”的思路:门线技术和越位(尤其是半自动越位 SAOT)高度客观,其他如点球、手球、红牌等由VAR介入往往更主观、易引发争议。
