High effigy drop rate due to their combat level.

Like I just said, I know that. I was referring to how I've never gotten 2-3 effigies in 1 glacor slayer task.

Their assumed drop rate is about 1 in every 80-100 kills

You should learn about Hypothesis Testing to avoid making erroneous conclusion based on a small sample pool.
Let X be the random variable denoting the no. of Glacor per effigy.
u0: X~90 (since you say the expected average is 80-100)
u1: X<90
Since variance is unknown and sample size is small,
Under u0, Test Statistic T= ((X-bar - u0) * sqd root n)/s ~ t(5-1) (you got a total of 5 effigies?)
Using one-tailed test at 5% significance level, reject H0 if p<0.05.
Hence to reject h0,
(X-bar - 90)* 2.2361 / (0.25*(n1^2 + n2^2 + n3^2 + n4^2 + n5^2 - (nTotal^2) / 5) < -2.132
where X-bar is the average kills per effigy required, n1-n5 is the no. of kills for each effigy (for a total of 5) in your sample, and nTotal is the total no. of kills.
Solve the inequality to find X-bar, and compare this with your actual sample mean to find out if your sample proves anything at all. Most likely due to the small sample pool you can't reach any decisive conclusion unless your sample is extreme (but the sample variance has to be small as well).

Since when Glacor is a slayer task??!@!?!
