Yeahh the best perfect evolution is 16 cards evo (though it's not recommended as you said, it's a pain in the ass). And yes there is no negative point in aiming it as the event stays for 2 weeks. Just let them stay in your present box (up to 90 days), and count how much you have to make either 5, 6, or 16 evolution.

Every 4* cards are able to do 16 evo. You do 6 evo if it's so tedious or you don't have enough cards. 6 evo is recommended because it's easier and it doesn't affect much to the card final form.

See this Speedster card for example and go to the GUR tab. Her card condition is similar to Pertcha on this event. Note that ATK/DEF does not matter on a card as you can always MAX it with arcanas. So ALWAYS see the soldiers count. Now see the solders on Speedster, her 5-evo yields 20906 soldiers, 6-evo yields 20916 soldiers, and 16-evo yields 20922 soldiers. Now ask yourself if 16 soldiers is worth to do with the resources you have right now? Though as I said earlier, you can keep them in the box till the event ends to see how it works out.

Hope this help your question :)
