tablet +30% distil not working?

I have run approx 10-20 map with 90% tablet drop chance distil and there is no difference between its tablet yield and a normally juiced map. The juiced map has the added benefit of giving higher tier tablets. I know the sample size might be too small, but if 90% increased chance yield 0-3 tablet drops while the average juiced map also yield 0-3 on average, per mechanics, then that does not feel right at all.

What I did:
I basically specced into tablet farming with max (magic) pack size and stack as may tablet dropping mechanics as i can (not boss). I was making so little currency and making no extra tablet compared to running rarity maps.
