At her size, unless she needs to take ~weeks off per month, and more importantly, at unpredictable intervals, she can afford to stream fewer days. Too many of them are incorrectly assuming that they need to stream daily, when (e.g.) MWF will suffice. What many viewers value over long streaming hours is predictable streaming hours[*].
I've observed many promising streamers stream daily and for too long, burn out, then unable to stick to even a reduced streaming schedule, thereby losing a substantial fraction of their viewers in the process. Then they became more demotivated, got sucked into a negative feedback cycle, and eventually quit streaming altogether. :-/
[*] Of course all else being equal, more time streaming ~ more income, but it's not sustainable, unless you're Amaranth & has an abusive spouse as her task master.
