What THCA percentage is actually strong?

Run the total-THC math first — THCA × 0.877 + Δ9 — and read the result the way dispensary flower reads: high teens is solid, low-to-mid twenties is strong, and numbers approaching thirty deserve skepticism before they deserve excitement, because potency inflation is a documented industry habit. Two calibration notes: percentage is not experience (terpenes, freshness, and your own tolerance move the felt result), and the difference between 22% and 26% matters far less than the difference between a verified COA and a recycled one. Buy the paperwork, not the biggest number.
