Asking for Advice on Strengthening My Hifz - Salam

Salam aleykum, I could use your advice and personal experiences with Quran memorization. I've been working on my hifz for years. The last surah I finished was Al-Muzzammil. In November I realized I had been linking surahs too quickly without properly fixing them in my heart and mind, which led to mixing up verses and having gaps in recall. So during December I focused on consolidation: intense review, improving understanding, and learning to identify verses by surah. I'm on holiday now so it's a good time to do that - when I'm working my business is very demanding and I get overwhelmed. The revision went fairly well, but because I was a bit tired I took a short break for a few days. There are three surahs I haven't fully locked in, but today I noticed Surah Al-Buruj - which I used to feel solid on - starting to slip. I felt really frustrated. My mu’allima reminded me that this is normal and that hifz is a process. My struggle is that I really want every surah to be perfect, 100% secure, before I move on. I crave that stability so I can recite without gaps; my tajweed can be improved later with my teacher. But I also worry I might be expecting too much, or moving too slowly. Is it reasonable to insist on mastering everything completely before continuing, or should I accept that memorization requires ongoing revision and that true anchoring comes with time and regular review? BarakAllahu fikum for any advice and duas.
