Literally EVERYTHING you say is wrong, I don't need to explain anything because anyone jumping in this conversation should know what qlvl and magic_level is, and no, magic level is not if the item is magic, rare, base or anything like that and qlvl is not if the item is normal, excepcional or elite.
Here, the formula to determine alvl, now tell for the 4th time that ilvl is the only thing that matter and be wrong again.
If (ilvl>99) then {ilvl=99}
if (qlvl>ilvl) then {ilvl=qlvl} ;
if (magic_lvl>0) then {alvl=ilvl+magic_lvl}
else
{
if (ilvl<(99-qlvl/2))
then {alvl=ilvl-qlvl/2}
else {alvl=2*ilvl-99}
}
If (alvl>99) then {alvl=99}
just get out, you have no idea of what are you talking about and you can't help here.
Looks like you use numbers.
Small charm ilvl 63 to 79 has alvl 49 which has a better chance to re-roll into a 3/20/20 compared to a Small Charm with ilvl 99. True or False? It is true, but better to have like an ilvl 65 charm just to be sure, reasoning is simple, less Prefixes and Suffixes that appear on higher ilvl items. Magical level means jack, you can only get Magical Small charms unless they have pre set. Now... what is Qlvl again in reference to this Small Charm?
A monster tc drops specific items in LoD, hence people doing Nightmare Andy runs for SoJ's in the day, the ilvl or qlvl you are referring to is based on the Monster Level of Andy and the drop chest from andy... also certain items can NOT drop (your so called Qlvl is what? oh, ilvl)
Now if you are talking about D2:R, I wouldn't know, however the basic areas are the same as LoD, as for new areas and items, those are different and have different drop tables (mdt or Treasure Chests) with selected things that can and can not appear.
Here is an example: Windforce can only be found on one specific ELITE bow, it has a Set amount of modifiers and ONLY those affixes apply to that item, if the Monster Treasure Chest is able to drop the BASE item of a Windforce (say from Hell Baal), its' ilvl is 99, however, RNG chance of it being a Windforce is what %, well the Mlvl is nulled, quality level is nulled, however if the RNG makes it have a Magical Level of RARE, it rolls the affix table to see what prefixes and suffixes apply to it, same for Magical roll prefixes and suffixes, HOWEVER, it will not roll into a Set item because there are no Set items with that Items Base.

Back to what I stated in a previous post... Does this imply that Imbuing doesn't require character level (clvl) when imbuing ilvl 99 items ... or Diadems (Elite base) with lower ilvls (has nothing to do with qlvl) for the alvl (affixes).
Imbuing is only Rare (yellow) so all modifiers (affixes / prefixes) for that type of item (helm/armor) will only apply. The alvl does play a roll.

Here is a theory craft that was debunked for crafting & re-rolling (or any cube recipes) ... does the ilvl of the cube make a difference when using cube recipes? ... the answer is No because it is based on the ilvl ot the item(s) used in the cube excluding Runes which don't have an ilvl
