Attack speed math

Just a simple question: why when I read in tooltip "attack speed + 10%" the value shown in character info is 111.11% instead of 110%?
Doing some calculations I discovered that 100/111.11 is 0.9. This means that normal (100%) attack speed is 90% of my current (normal +10%) speed. I'm quite sure it is intended, but I cannot get the logic behind that.
Can anybody explain me if it is correct or not?
Also, when showing the difference between current (111.11) and previous (100) speeds that difference (+11.11%) is shown in green color, as if it is an improved stat; instead it should be red (lowered stat), according to me.

I think the coloring part is done in tome-3.9.41\mod\dialogs\CharacterSheet.lua line 380
Code: Select all
text = compare_fields(player, actor_to_compare, function(actor) return (1/actor:combatMovementSpeed()-1) end, "%.2f%%", "%+.2f%%", 100)
where is inversed is not set
Code: Select all
local compare_fields = function(item1, item2, field, outformat, diffoutformat, mod, isinversed, nobracets, ...)
so I think it should be
Code: Select all
text = compare_fields(player, actor_to_compare, function(actor) return (1/actor:combatMovementSpeed()-1) end, "%.2f%%", "%+.2f%%", 100, true)
the strange thing is that the same logic (1/speed) is not applied to other speeds
Code: Select all
text = compare_fields(player, actor_to_compare, function(actor) return actor.combat_spellspeed - 1 end, "%.2f%%", "%+.2f%%", 100)
...
text = compare_fields(player, actor_to_compare, function(actor) return actor.combat_physspeed - 1 end, "%.2f%%", "%+.2f%%", 100)
edit: the above code is for "General" page - "Attack" page uses instead this code (tome-3.9.41\mod\dialogs\CharacterSheet.lua line 571):
Code: Select all
text = compare_fields(player, actor_to_compare, function(actor, ...) return actor:combatSpeed(...) end, "%.2f%%", "%+.2f%%", 100, false, false, mean)

This is an energy based game and the attack speed concept uses the attack costs less energy mechanic. There are been some changes from a while back (mostly due to crazy stacking) but the numbers still stood from that time.
This should be changed but: Less attack speed in tooltip = a good thing atm. If you see the tooltip on a quick weapon it says attack speed 90%, but that actually means it just costs 90% energy to attack so you get 11,11% more attacks per turn.
It's a bit of a mess in terms of understanding but it seems but be stacking much better than it used to a while back, the tooltips just need some fixing.

thanks Dervic!
an in-game better explanation is definitely needed!

I've checked again.
when activating "Precise Strikes" (reduce you're attack speed by 10%) in character screen - "General" page there is a line with "attack speed -10.00%" and in the "Attack" page the Main Hand speed is 111.11%.
So it seems that in character screen higher speeds are bad. the exact percentage (11.11% slower) is still not 100% clear to me, but it's ok.
For sure having (+11.11%) in green color has to be changed, as it should be red.

This is quite unrelated but still about a.spd.
How does different a.spd on 2nd weapon affects the character? Does it just use slowest or average a.spd to determine how many "energy" or amount of turns the attack uses, or will the weapons desynch and attack at different time?
