You can calculate exactly how much you've made, but be sure to also include the curation rewards in your calculations. On the other hand, it's impossible to know what you've missed out on, in terms of upvotes. You can forget a Curie upvote if you use bots (in most cases, not all).
It's for yourself to decide how you want to proceed, just don't fall into the trap of lying to yourself. I did that and it happens quicker than you think ;)
