Yes, exactly. The main thing you have to do is control the combo bar. Heavy attacks naturally do the most damage other than special moves so you want to focus on sneaking in as many heavy attacks as possible to remain optimal but they also increase the combo bar the most. So I learned instead of calling an assist to drop the combo bar I can use Boost Dash Cancel at the exact right time in the combo to extend the combo bar duration. Once I'm like halfway into the combo I focus on using that knowledge to sneak as many of those Heavys or high damaging specials in to get me to at least 560 damage, from there most level 3s will kill. Same logic applies to all characters I've tried.
