Sometimes the EV spreads just don't work at level 50. For example, Gliscor's analysis says 244 HP EVs so it'll have a number to stall out with Poison Heal & Substitute. Its HP is 352 at lv 100, but at lv 50, it's 181, which I'm pretty sure wouldn't work.
Another issue is that at level 50, 8 IVs would result in the same stat number if you just used 4 IVs. (If someone can explain this better for me, please do it).
