I am trying to understand how attuned enhancements work

[Hitback]

Set bonuses seems pretty straightforward, you lose bonuses when you go more than 3 levels below that of your slotted enhancement. So for example a level 50 enh will count towards set bonuses up to lv47. Purple and Pvp IOs are exempt. Attuned enhancements will keep their bonuses up to 3 levels below the minimum of the level range of the set, so for a 25-50 set, they would stop working below 22.

So if you care about keeping your bonuses, attuning your non-purple/PvP enhs is optimal.

 

What I'm having trouble with is how the %values (dam/acc/rech/etc) of the enhancements themselves work when exemplaring. 

According to wiki: "Level 32 is a key breakpoint. If you are 33 or higher, you can Exemplar as low as 32 with no penalties no matter how big the drop is."

If I am understanding this correctly, a level 50 enhancement will work at its full values as low as 32. Whereas an attuned enhancement would drop its values to the level 32 version of the enhancement.

 

So, my question is, when I don't care about set bonuses, is it then better to keep enhs unattuned even when exemplaring?

 

EDIT Ok, if found this on wiki: "When exemplaring, the effective aspect enhancement is figured as if it were the current natural level of the character, or, the maximum level of the range of enhancement if the character has outleveled it. Then the normal Exemplar Effects on Enhancements apply.

So, e.g., if the Attuned Enhancement had a range of 30-40 and the character was level 45 exemplaring to level 15, then the effective aspect enhancements would be the same as a level 40 enhancement exemplared to 15."

 

So that means that attunement doesn't actually affect/improve how enhancements exemplar down, but it's purely about maintaining bonuses then.
