I guess nobody believes Zimmerman's commentary on the NEN call during the third interview with Serino and Singleton.
It's not as if there aren't good reasons for doubting it. I think it makes a poor fit with Zimmerman's earlier SPD interviews. Zimmerman often expressed uncertainty during the NEN commentary, more frequently than in the earlier interviews. And there are the timeline issues.
Of the 'waistband' event, Zimmerman said 'I think I'm still at the clubhouse, yes' (2/29-3, 3:04-24). This was the first time in the NEN commentary that Zimmerman qualified a statement about his location.
Before 2/29, the hand in the waistband was invariably associated with Martin circling the truck, and it was never suggested that there were two such incidents. The circling was always on TTL if its location was specified. Zimmerman twice denied that the circling was at the clubhouse.

Singleton: OK. You pass him, and this is where he's looking in the houses. OK. And then, where do you go, when you realize, you said he comes, and he circles your car?
Zimmerman: No, ma'am. I lost contact of him, as I was trying to get through, because you have to-
Singleton: So does he continue past you?
Zimmerman: Yes, ma’am.
2/26-2, 2:15-25
Singleton: OK. And, you said at some point he comes back and circles your car? Has he already done that?
Zimmerman: He looked into my vehicle, but he didn't circle it at that point in time.
2/26-2, 3:19-30
Singleton: We're just, we're gonna X this one out, because it's not where you meant. You meant that you came around here, and ended up here.
Zimmerman: Yes, ma'am.
Singleton: OK. OK. You ended up here. And then, is that when he circles your car?
Zimmerman: Yes, ma'am.
Reenactment, 3:33-4:00
Zimmerman: And I saw him walking back that way, and then cut through the back of the houses. He looked back, and he noticed me, and he cut back through the houses. I was still on the phone with non- [recording seems to skip].
Sgt. Smith: Mmhmm.
Zimmerman: And then he came back, and he started walking up towards the grass, and then came down and circled my car. And I told the operator that. He was circling my car. I didn't hear if he said anything-
Sgt. Smith: Right.
Zimmerman: -but he had his hand in his waistband.
CVSA, 26:56-27:49, 6:45:33-46:26
Zimmerman: The operator asked me if I could get to somewhere where I could see, or at least give them a direction of where he was headed.
Erwin: Mmhmm.
Zimmerman: And I said "Yes." So I pulled out, and I drove adjacent to the clubhouse. And, I was unfamiliar with the street name. The operator asked me what street I was on. And it's not the street that I live on. It's a side street that cuts through the neighborhood. And I told him I didn't know. And, they said, "We need to know - " When I was at the clubhouse, I gave them the clubhouse address. And, they're like, "We need to know what house you're in front of." And I said, "Listen, if you come to the clubhouse, go straight, and left, and you'll see me there." At this point the guy walked around my car. He had his hand in his waistband.
There is no circling of the truck in the NEN commentary, nor in the earlier parts of the 2/29 interview.
2/29-1, 21:31-51
Serino: What do you think his mindset was? I'm telling you right now, the kid has no violent background, no violent tendencies that we can find. What made him snap? He's not on drugs. Can you fill in that blank?
Zimmerman: The other thing was, when he walked up to my car, he reached in his waistband, and held his hand there.
On 2/29 it was walking up to, no longer walking around. The investigators didn't ask what happened to the circling. Singleton echoed Zimmerman's language.
2/29-1, 22:32-41
Singleton: I'm not, I still don't understand. When he walked up to your car, why didn't you say anything to him?
Zimmerman: I guess fear. I didn't want to confront him.
In the NEN commentary, Serino asked Zimmerman what was happening as he gave the dispatcher directions.
2/29-3, 4:46-5:08
Call:
Zimmerman: Yeah. When you come to the clubhouse you come straight in and make a left.
Serino: What's happening now? Are you guys walking now? Is he walking?
Zimmerman: No, that's, I was parked where I could see him now.
Singleton: So you're definitely not in front of the clubhouse anymore, at this point.
Zimmerman: No. Hmm-mm. No.
Serino: So you're ahead of him?
Zimmerman: No, I was behind him.
Has Martin circled the truck already? Or is he about to reach the
'darkened area of the sidewalk', then quickly turn on his heel to approach and circle the truck?
The darkened area is, I estimate, about 140 to 150 feet from Zimmerman's truck.
A
Honda Ridgeline is about 17 feet long, and about 6 feet wide. Walking around it from the front would be a minimum distance of about 40 feet.
Martin has about 15 seconds before he starts running. He will need to walk at about 12 feet per second to approach and circle the truck in that time. Then he will need to run at close to 30 feet per second, the speed of an Olympic sprinter, to reach and turn the corner so that Zimmerman, having presumably turned on his high-beam headlights, can observe Martin running 'Down toward the other entrance to the neighborhood'.
