Excellent math.

I will take this into consideration when skilling up now.

Edit: Unless it rounds to the nearest which would make Lvl 5 minus 2.

Last time I checked the math, it dropped another PG at Level 5.

Doublechecking ...

Bsc - 2.0, 1.9, 1.8, 1.7, 1.6, 1.5
Adv - 4.0, 3.8, 3.6, 3.4, 3.2, 3.0
Pro - 7.0, 6.7, 6.3, 5.9, 5.6, 5.3

Basic ... optimization saves 0 PG.
Advanced ... optimization saves 1PG level 3.
Prototype ... optimization saves 1PG at level 2 and another 1PG at level 5.

EDIT:

Before you train this skill, please read this.

Fitting Optimization (5% reduction to PG usage per level) 6x (1,865,520 SP to max) (requires Proficiency 4)

The suit will add PG from every module together before round the number.
So when we add some module on top such as cloak or rifle which has PG reduce bonus, it will be like this

Pro Knife - 7.0, 6.7, 6.3, 5.9, 5.6, 5.3

Adv Cloak - 12.3, 12.3, 12.3, 12.3, 12.3, 12.3 (scout lv5)

Total PG - 19.3, 19.0, 18.6, 18.2, 17.9, 17.6

Actual PG - 19, 19, 19, 18, 18, 18 (After round number)

In practical, it's imposible to get 2PG reduce even you train it to level 5

Last time I checked the math, it dropped another PG at Level 5.

Doublechecking ...

Bsc - 2.0, 1.9, 1.8, 1.7, 1.6, 1.5
Adv - 4.0, 3.8, 3.6, 3.4, 3.2, 3.0
Pro - 7.0, 6.7, 6.3, 5.9, 5.6, 5.3

Basic ... optimization saves 0 PG.
Advanced ... optimization saves 1PG level 3.
Prototype ... optimization saves 1PG at level 2 and another 1PG at level 5.

so is it worth 1,866,000 skill point NO! not even for a Minnie scout who is low on pg. if it was 10% per level sure.

I was under the impression that CCP rounds down the numbers rather than traditionally round them up. In fact, according to Protofits.com the PG requirements for a pair of Ishukone Nova Knives is reduced by 2 PG at level V.

Anyways, you will be amazed how often you can come up with awesome knifing fits but then immediately trash it when you realize you're 1 PG short of the demand regardless of maxing out all other core skills. Even 1 PG can go a long way especially for a dropsuit like the Minmatar Scout which people often say has 'meh' PG availability.

Advanced ... optimization saves 1PG level 3.
Prototype ... optimization saves 1PG at level 2 and another 1PG at level 5.

I did train Optimization up to lv3, and I monitored PG on my suit every iterator.

Test 1: Adv Min Scout, Adv Knife, Adv Cloak
Result: 0 PG, optimization LV3.

Suit 2: Adv Min Scout, Pro Knife, Adv Cloak
Result: 1 PG, optimization LV3.

I also test it on protofit, and it free up only 1 PG even I have Optimization V
Optimization V will free up 2 PG only fitting Proto Knife alone

Conclusion: Worth to train only up to lv3

What do you think of my recommendation to buff it to 6% per level instead of 5%? Is the proposed return even worth it for the investment? Keep in mind that we are dealing with percentages effecting very small numbers here.

@ Maken Tosch

We should not just fix it by put 6% on NK Opt alone because the conventional round number apply on all weapons Opt skill. So the same goal must apply to all weapons, and it could be a crab load of discussion about fixing this skill, I bet, Rattati already has too much work. Also the Optimization skill topic was bought up many time in the past and then fade away from time to time.



My intent here is to remind people about this effect before they design to train this skill higher than lv3.
