So... did he have the bat with him in one hand, gun in the other hand as he chased Reeva into the toilet (on his stumps). Did he have his legs with him too... one tucked under either arm as he chased her with gun in one hand, bat in the other? Even so... he still had to pause and put his legs on after the shots....sooner or later. He did have to make the three phone calls.. It really does not make sense (Nel Test).
I don't think he shot at 3:00. I think 3:10/3:12
AFAIK the 03:12 was from Mr. Johnson's notes where Roux said there was a woman screaming at 03:12. Unless I missed another reference?
Baba said that shortly after 03:00 a guard reported shots. Mrs. Stipp looked at her clock and it was 03:02 (3-4 minutes fast. Shortly after that she heard the first set of sounds.)
Your other question was what had to have happened
after the shots at 03:16-03:17.
The things you mention here (the bat, the legs, the gun) could all have happened
between the two sets of sounds.
They argue.
She's locks herself in the toilet.
He gets a bat.
He hits the door and makes a hole/holes in the wood in the process.
(Witnesses hear the first set of "shots." Willow wood on a Meranti door.)
(They also hear terrified screams.)
He goes to the bedroom.
He puts on his legs.
He gets the gun.
He goes back to the bathroom.
(Witnesses hear the intensity and fear in the screams escalate.)
He shoots her through the door.
(Witnesses hear the second set of "shots.")
(Witnesses hear the screaming stop.)
He uses the tip of the bat as a lever to crack the door then breaks it open with his hands. The straight crack runs through bullet hole D.
He drags her into the bathroom.
At 03:18:45 the texting and phoning starts.
After the 03:22 call he carries her down the stairs.
She dies on or at the bottom of the stairs.
