The people who decided to 'nitpick' over times were the Tapas group. Almost immediately they concentrated on producing a group timeline, followed by another a few days later. Neither of them are definitive because individual statements don't match them.
Why do you think the waiter and Steve Carpenter didn't notice how late the Paynes and Dianne Webster were that night? According to the group they were not all seated by 8.45 (the waiter) or 8.30 (Carpenter), they weren't all seated until 9pm. Despite the Carpenter's table being adjacent to the group's table he never noticed those three empty chairs. It seems they and the waiter would have given the Paynes an alibi if they had needed one, even though they weren't there.
So who didn't recall the true scenario? The witnesses or the group or both? If we can't be sure about their time of arrival, we can't be sure about the times of the checks or of the alarm being raised.
Nope. That's not what nitpicking is. You really need to start looking words up in the dictionary before you post as you don't seem to know what they mean.
Nitpicking - fussy or pedantic fault-finding.The Tapas group were just trying to get the timings as accurate as possible because they knew how significant it might be to the case. By collaborative effort, you can increase the accuracy of the timeline better than as individuals. I'm sure you find this activity of collaborating highly suspicious, but really it was actually a very sensible thing to do. If person X cannot recall the exact time they did something, but they do recall it was about 5 minutes after person Y did something, then it is possible to put a more accurate time on person X's event if person Y
does know what time they did their thing. See how that works?
Yes it can work the other way too, so if person Y is incorrect about their time, it can knock on the accuracy of X's time. But when you have so many people helping to verify the various comings and goings, because they were all there and interacting, the accuracy of the timings DOES increase moreso than if recounted individually.
Do I think the times given by the Tapas group are 100% spot on? No. But just because a bar worker thinks everyone was sat by 8.45, it does not make his timing more reliable just because he has "no reason to lie". I very much doubt he was there with a stopwatch, watching and counting the group members like a hawk.
