For a novel and considering the recommended size of a tapas chapter. I have seen that it is better to have 2 chapters per week rather than 1. That is on Tapas. Basically two chapters of 3-5 minutes work better than one chapter of 6-10 minutes.
That is on tapas not on other platforms. On other platforms I notice a tendancy to having 1 longer chapter rather than two. When you decide how many chapters you should publish per week and which schedule you should take in mind your target audience. In this case the target audience is tapas readers.
Now your poll might not help you as you may have hoped since many here are authors and we are not your target audience. Instead I think you should poll your readers and see what they think about it.
P.S. You should also note that the frequency in which a novelist and an artist update their stories are not the same. Be careful in that sense since you are clearly a novelist.
P.S.S. Having said all that remember to not chew more than you can.
