I would like some observations and opinions of the maximum number of page list blocks on a page.

Q1. How many page lists on a page?

While at it, same question about autonav blocks.

Q2. How many autonavs on a page?


Now a bit of explanation.

Both blocks can be expensive in processing resources, so every extra page list or autonav on a page can slow it down. However, some designs use multiples of these blocks.

I am developing some addons that, for reasons of convenience of design, will have a fixed limit on the number of page lists or autonavs on a page the addons can work with. I don't want that limit to be too small. But I don't want it to be unnecessarily large and cause unnecessary bloat in the addon interfaces.

So please, either just quickly reply with some numbers for Q1 and Q2, or add whatever explanation you consider useful.
