In a small community without a learned ba'al koreh, it can be difficult to assemble enough readers to read the entire weekly parsha to a suitable degree of proficiency. Is there any provision in halacha for reading less, provided the entire torah is read over the course of the cycle (which will take more than a year in this case)?
I understand that some have a triennial cycle instead of the annual one (I've heard this said of Israeli communities in particular). I have the impression, perhaps mistaken, that those communities have a received tradition of the triennial cycle; they didn't just do it for expedience. Here I'm asking about a community that would otherwise read the entire parsha and complete the cycle in a year, except that they don't have enough good-enough readers. Short of fixing their ba'al koreh deficiency, what can such a community do?
