No visuals at 120ug

I’ve taken acid a total of 5 times. My first 2 trips were around 70-100ug and I had very slight visuals but only if I really focused on it. I’ve found the headspace on 120ug very manageable and after the peak is over I was basically sober (only felt like it, I still couldn’t communicate properly and had problems with basic tasks). Recently I’ve tripped again each time with 120ug where I definitely had a stronger headspace but overall it felt underwhelming and barely had any visuals. I’m getting new tabs (differently dosed) and I wanted to take 2 (≈160ug) or 2.5 (≈200ug). If anyone else barely has visuals at 100ug what dosage does/did it take for you to see them? Is the jump from 120-160/200 very strong or still manageable?
