What "ready" looks like

First-15-minutes checklist: 100% (muscle memory for day-of)
Pre-competition-week checklist: 100% (practice drills complete)
Top 4 lessons (Samba, MikroTik NAT, SSH hardening, Backups+Cron): all drills at 100%
Terminal drill: 4/4 goals
Hardening checklist: at least 50% (you will pick up the rest during competition)

Hitting those thresholds means you have internalized the highest-ROI defensive patterns. The remaining 20% of skill is all about speed under pressure. and that only comes from practice, not from reading.
