jewels increased dmg question with melee phys and melee dmg on full life gems

im sure that these 2 gems works with increased phyisical damage with weapon/while holding a shield and increased physical damage mods on jewels

but what about increased damage and increased melee damage? do these 2 increase my DPS as much as the previous 3 phyiscal mods using 100% more physical damage from those 2 gems?

are increased damage and increased melee damage additive to the final dps? while the physical damage mods are good with the more melee physical damage mechanic of the gems?

'Increased melee damage' and 'increased damage' just have less conditions to apply than 'increased melee physical damage', for the first one damage can be of any type, it just has to be delivered via melee attack, and for the second one there are no conditions, it works on any damage type and form in the game. So, the question about increased damage bonuses is only - do they apply to the damage segment in question, if they do all of them will add together to form one damage multiplier.

And those two support gems give you 124% more damage together, not 100%, multipliers don't stack.
