Peaking for early intermediate & early-ish intermediate - Free coaching advice?

My wife and I are going to our first strengthlifting meet next Sunday 4/29! I’m her coach, however unqualified, due to being in the middle of nowhere and unable to afford online coaching currently.

She’s only been intermediate (erm - post-novice?) for about 3-4 weeks, and so I’m wondering how you might peak for a lifter at this level. I was planning on taking some advice/inspiration from this - Starting Strength Coaching Directory - On tuesday having her do a bit of reduced volume on the lifts, a heavy single @8, 3x5 (she was doing 5x5) for squats, heavy single @8 for press, then 3x5 (she was doing 5x5). Maybe 1x5 @8 deadlift (she was doing higher volume deads like 4x6 or 3x8 for her “squat focused” days)? Then on thursday light (80%) deads (3x3), light bench 3x3), light squats (3x3) and call it good?

We both did a “mock meet” today where we ran our 1st/2nd attempts. I plan on having a light day on thursday and calling it good. I’ve been post-novice about 7 months so I thought that I would qualify for a regular peaking plan - or should I do more next week? I’ve been doing a 4 day split, then tapered to a three day split last week. Before that I did versions of Texas Method (with more volume) and HLM.

We’ll take any help we can get!

After the meet she’ll be doing the bridge, and I the hypertrophy template, so I’ll stop bugging you guys w/ programming questions, haha!

Sorry I’m just getting to this now!

On day 1 of meet week for post-novice lifters I’ll often have folks hit their squat opener with a couple lighter back-off triples, a fairly heavy bench press (often above the opener) followed by some challenging work sets, and work up to their last warmup on the deadlift. Day 2 of meet week will be around the last warmup on the squat (or heavier for lightweight/female lifters) with some lighter backoff doubles, and bench opener with back-off sets. Day 3 off, then compete!
