Hello
I just discover your website and I'm impressed and thankful for your work. I have an idea regarding a temporary mean price ( maybe last 30 days ) that could make a more accurate price of the card, as at the beginning the card prices has bigger volatility as well as boosters has been discounted by extra 100 bfp which clearly have an impact on cards prices. That temporary mean price could be reveal for each card as well as booster evaluation, for example I run a spreadsheet to evaluate nature booster estimated by current price at time was 544 bfp (same as your website) but mean price evaluation was 457 bfp that quit big difference. I think this could help many people to make mind which booster to buy/or not.
