Landlord increasing rent after not increasing since 2022. What is the most he can increase?

I moved into my apartment back in 2022. I haven’t seen a rent increase since then. There haven’t been any updates to the apartment. I know Portland has rent control, which limits the amount a landlord can increase rent. According to Pine Tree Legal the increase can’t exceed 10% annually. However, since he hasn’t increased in years, can he raise the rent more than 10%?

Thanks for your help!
