Yeah, the excitement gained from opening chests is probably my biggest motivator for boosting my power. Since gains so far are so small XD
$2.99 was my base rental cost and I got rewards with an estimated value of $4.99.
$1.32 was my final net. It would have been $2 if not for my mistake.
Thanks for mentioning valuation of chests based on drop probability. I hadn't considered it before and was mostly basing it on the actual stuff I get. It's a good angle to look into. I'll probably include it in my next season's rewards post. But for a quick overview ...
Based on Splinterlands loot chest estimator, current chest value is $0.225. With the last season, I got 16 more chests. So that's 16 x $0.225 = $3.6. My actual rewards were higher. I got lucky by getting one booster pack with a 1.50% drop rate :)
