UOB One Credit Card sign up promotion?

Hi! What's the usual sign up promotion amount that UOB One offers for new credit card sign ups?

​

Saw that they're running a S$300 one right now from 1-31 Oct if you spend S$1500 within 30 days. But I've already maxed out my spending for this month from the recent 10.10 sales. Thinking of waiting for next month's sign up promo, so would like a gauge of how much UOB usually gives out for sign up promo!

​

Thanks so much :)
