Arcane Recovery Macro

Question about Arcane Recovery Macro.  I have a macro that doesn't work quite right..... the Wizard 4th level character has 2 slots to recover for Arcane Recovery. I have put it in the resource_class box. What I want is that when I click on the macro, it automatically deducts those 2 slots from the resource_class. Then the character manually adds the slots in the character sheet spells, no problem with that.  The only way I can think of is to subtract 2, and every time the level is increased by 2 modify the macro and subtract 3, then 4 and so on. I don't know if there is a way to configure the macro without tweaking it every 2 levels. !ammo @{selected|character_id} class_resource -2 Arcane Recovery (for example) This is my code &{template:atkdmg} {{normal=1}} {{mod=Frantz}} {{rname=ARCANE RECOVERY }} {{dmg1=[[@{class_resource}-@{class_resource|max}]]}} {{dmg1type=slots left}} {{desc=You have learned to regain some of your magical energy by studying your spellbook. Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your wizard level (rounded up), and none of the slots can be 6th level or higher. For example, if you're a 4th-level wizard, you can recover up to two levels worth of spell slots. You can recover either a 2nd-level spell slot or two 1st-level spell slots.}}  !ammo @{selected|character_id} class_resource -class_resource|max Arcane Recovery

I remake the macro..... as &{template:desc} {{desc=You have learned to regain some of your magical energy by studying your spellbook. Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your wizard level (rounded up), and none of the slots can be 6th level or higher. For example, if you're a 4th-level wizard, you can recover up to two levels worth of spell slots. You can recover either a 2nd-level spell slot or two 1st-level spell slots.}}  !ammo @{selected|character_id} class_resource -2 Arcane Recovery With this macro i need to manually change every 2 wizard level increasing by 1 in the !ammo section. But it works as well.
