As we have no idea of what the crime scene looks like, it's impossible to tell how long the attack went for.
The perp may have been holding her down yelling at her for god knows how long. 'He' may have paused sometime during the attack then thought to give her more to make sure she was out of the picture. It is not unheard of where a perp has thought the victim to be dead, then the victim moves slightly (or goes into death throes, yes bodies do spasm) and they panic thinking they are still alive and begin attacking again....so 10 to 15 minutes is not impossible, unfortunately.
Someone who begins strangling a person will almost always finish 'the job' unless the victim is able to fully escape the situation or is extremely 'lucky'. And if a perp is unsuccessful at the strangulation, they then tend to bludgeon or knife their victims repeatedly. Once a person begins to murder someone by strangulation, it's not as though they can fail and think to themselves "oh well, that didn't work, I'll do it another time".
Sometimes that 'rage' is actually directed at themselves as they see themselves as a failure, not being able to complete a 'simple' task as strangling someone. That rage then turns outward at the victim and the result is often 'overkill'.
