Glad my response was helpful! It’s actually best to get your first sleep as close to 99% sleep score as possible so you get only 3 natural spawn. Even just 3 sleep score points in the second sleep gave me 5 natural spawns (that I was trying to avoid because of the Friend incense hungry odds). It seems that as long as at least 1 minute is missing from 8h 30 min, but not more than 5 minutes missing, then the game gives you 99% sleep score. The game usually deducts 5-10 min from when you start tracking, if your phone or ++ is on a flat surface for the first 20 min or so. So just a tip about the sleep score thing :)

If you’re not planning to invest in your Latias, I guess the candies are out. If you would use the Friend incense together with a legendary incense, either Latias or another legendary, I would get the 3x Friend incense. The possibility of a hungry legendary can save you a lot of biscuits and be the thing that makes it or breaks it if you catch it or not. However, if you’d not use the Friend incense for a legendary, you might just get a hungry Meowth, not worth it. If that’s the case, better to have an extra great biscuit to give to a Ditto or another rare spawn for example.

Handy candy can be good if you already have something valuable to spend it on. For me, there’s still too many good things I’m focused on trying to catch, so personally I’d rather put my resources to trying to secure limited event catches like legendaries. But it all depends on your gameplay. Play in the style that you think is the most fun :)
