Sadly, there's nothing "advanced" about these tips, just basic common sense anyone with half a brain and have been playing for more than a month should have if they don't want to waste resources and gain nothing. And even at that standard, you got the magic numbers wrong on some rebates.

To echo what everyone else has said already, no, the time-limited cave keys don't count toward milestones. So the magic number for cave rebate is either 1050 or 2100 keys. Don't matter which one. If you have less than 2100 ready, just go for 1050, if you had over 2100 ready, go for 2100.

For Refines, there are group shop, monthly events, and groceries stores for medium and adv refs now, not just events only anymore. And since it's "advanced" tips, we should assume most people reading this would be half-way through with basic refined if not all the way through. It's better to save up for med and adv refs since basic runes are practically thrown at your face left and right.

For Charm, anything less than 500 (100 charm boxes) belongs in the "basic" tips for newbie who needs to gain power fast and can't afford to save and wait. But since you decided to call this "advanced" tips, then you'd want 500 or 1k mark. 500 is best in general, but 1k is also a good way to get a lv6 rainbow mags, so it depends on your priorities.

If this was "basic" tips, then yes, what you have would be barely acceptable, but most people looking at "advanced tips" would be hoping for something they don't know already, and unfortunately, this is not it.
