There are a number of tips by great HCI researchers about writing good rebuttals. You can refer them to prepare your rebuttal. If you don't have much experience in rebuttal, it's always good to read it before rebuttal period to save time.

As a PhD student, I don't have such great tips, but I can share tips to shorten your rebuttal, which actually helped me while writing CHI rebuttal last year. They are somewhat dirty, but useful.
For the record, I learned most of them from my colleague, Huy Viet Le.
- Passive tense --> active tense
- #AC --> #R
- And, but --> ;
- did not --> didn't or didnt. Use it at most once, only when you are desperate.
- Previous work --> prior work
- Cut a long sentence into two sentences. It can save space for connecting terms such as which, that, etc.
- Make abbreviation e.g., KnobSlider -> KS
- Randomly remove space that is not notable. E.g., We will add suggested statistic analysis. (R1, R4) -> We will add suggested statistic analysis.(R1,R4)
Keep in mind that your writing is academically qualified. I put additional links that give you more tips.
