Second opinion needed

[AusPEteach]

I have been training a fellow the past 5 months, he has been training for his first powerlifting meet in March. I have attached a spreadsheet of his training.

Stats
Bodyweight: 131kg -> 124kg (recently has been losing 2kg per week)
Squat 60kg 3x5 -> 150kg 3x5 (180kg 1RM)
Bench 60kg 3x5 -> 88kg 3x5 (92.5kg 1RM)
Deadlift 80kg 1x5 -> 165kg 1x4 (172.5kg 1RM)
Press 40kg 3x5 -> 59kg 3x5
Rows 55kg -> 65kg

I want to get your opinions on a few things.

1) At the rate he is losing weight he will be under 120kg within two weeks with 3 weeks before the meet I am concerned this weight loss will compromise his competition attempts. If he builds up to a PR squat before the competition will that be a good indication that his attempts are safe (common sense I know but I want to make sure)?

2) Adjusting linear progression to peak for competitions: In the spreadsheet you can see he has a deload and then works up to a PR before the competition, I have seen this done in classical periodisation. Does any one have experience with adjusting linear progression for a novice in this fashion? Any advice?

Edit: This forum does not allow excel sheets to be attached so here are pictures which have been compressed by the forum.

If I lost 2kg a week for 5 weeks in a row I would be a physical wreck, fantasizing about food all day and would no longer desire to be a competitive person. But that's just me.

The person losing the weight is also over 300 lbs, so roughly 5lbs a week isn't as big hit on them as you

Last year I lost a mere 6kg in 9 weeks (102.5kg -> 96.5kg) and I completely stuffed up a competition because of it, this is the cause of my concern.

My thoughts exactly, if all goes as I plan he will squat 157.5kg > 175kg > 180kg even easier than he did last week.

I was surprised that the bench press and dealift attempts were not successful but is is apparent that he is good at squatting and bench press progresses much slower.
