I am in the same range but after looking at your breakdown, you need to focus on LG. That is the most 'learnable' and you are missing too many! I'm excited for you. It's so possible to get -1 or -0 on LG, especially with 7sage.
Is there a stipulation for how many times you can ask for a coupon? Pandemic has been rough on my motivation so I did this in July. I am feeling really good but not good enough for August. Let me know if anyone has insight.
