Sector expire between n+4 and 4n+4 caused too much replot at beginning. What about change it to n+4 and 4n+16? Maybe n+8 and 4n+32 would be better.

It is done that way for a reason and more frequent replotting initially is an expected behavior.

I recommend you to read resources mentioned in [What triggers a sector to start replotting](https://forum.autonomys.xyz/t/what-triggers-a-sector-to-start-replotting/1688) to understand why it is absolutely crucial for the protocol and why is not better for network resiliency to change the way that you suggest (of course you’ll be happy to do less frequent replotting, that is clear) unless you can prove that it is.

Thank you for your reply,Nazar. I’m sure you and your team would always make the best decision.  
I’m not technical. I read your link carefully. But unfortunately, I still cann’t understand why set that parameters.

If we set it too high we’ll likely lose the history, which will be game over for the blockchain. As simple as that.
