Engineers Do you stack rolls or reroll every time?

In a video from ChaosWulff (iirc) he was engineering. I wondered why he clicked "try again" on every roll that was "good" but not "good enough" for him.

Should I question my method of accepting a "good roll", e.g. 40% FSDRange5 and then see what a new roll adds/decreases?
If I like it ... I accept it and reroll again. The red and blue bars tell me when the chances get low to get even better.
I admit I do this all the time and got FSDRange5 on my 3 ships to 46% - I know this is not the ceiling but it came with very few rolls, so I am ok with it.

When levelling up with an engineer I found it interesting how high you can get with lvl1 rolls only by stacking them en masse.

==> So do you know which one is the better approach - by mathematical / propability calculation means?
 
If I get a good roll on e.g. a FSD, but not perfect, I apply it and then make sure to put that FSD drive on a storage ship (or in module storage after 2.2 is released). Never know when you'll have use for a good-but-not-perfect roll. Afterwards, I make new attempts on a fresh FSD so the good rolls aren't wasted.

but it wont be wasted if you dont apply it
 
I wont go to an engineer unless I have at least 10 rolls, normally 15 (except pd, exquisite focus crystals and all). For fsd and dirty drives I'll take the first roll that is over the maximum, ie all my fsd's are over 50%.

Go in bulk, don't walk away disappointed...
 
I also keep each attempt that's better than what I landed with.

Most every time I've visited an Engineer I have just 1 to 4 attempts worth of materials, so I use those up and take the best I get.
 
In the past I've applied and re-rolled on top of it. However, I now not only roll on clean modules but also reset the instance before each roll. I've found that the first rolls have a higher percentage of good outcomes. At least, that's my current theory. PITA for sure, but getting mats is even more so.

I don't know about everyone else, but I find the fact that you've spent a lot of time trying to gather all the materials required, doing all the tasks to unlock the engineer, THEN doing more tasks to get to a higher grade, I think it's really unfair that you get a random result when you decide to engineer a module. It should be a guarenteed result, not a result you may not like or have no clue how it may end up. On top of this, Grade 1 and in some cases Grade 2 seem almost pointless. There should have just been 3 grades. Small effect, medium effect and large effect.

The RNG element is there to keep people hooked and playing. It's just a thinly-veiled slot machine. It does kind of tick my OCD off to know that PvP metagaming perfectionists running around in Open Play have better ships because they threw the dice at the wall more than I did, but that's the way things go, I guess.

Gambler's fallacy.
 
The problem I have with engineers is that the information given is pretty meaningless - if I'm doing a FSD range upgrade I want to know how much further the upgrade will get me. Does it tell me this? No. No it doesn't. It's all optimal mass and fuel per jump etc.

So anyway, in response I tend to try and make sure I've got a few rolls worth of materials and then burn a few - generally the upgrade is better than a baseline (FSD range for example) but being able to tell whether it's a poor roll or not is the hard part.
 
I apply if I get a good roll then start tweaking with other rolls. The outcome is always better for me this way.
I do the same. Got my 54.8% FSD this way. Reason being, you can only get one secondary bonus per category per roll. That secondary has a set maximum. So if I get, say, a 49% FSD roll due to a secondary and apply it, the next roll I could get another secondary that improves it again by the same amount.
.
Also works well on grade 1 rolls. I like to do low power efficient grade 1's on my power plants. Just keep rolling until I get good heat efficiency, mass reduction, and power neutral or increase (all 3 bonuses and no negatives).
.
I know it's all a slot machine but at least it is possible, with enough rolls, to stack some good secondaries.

My Cutter got a 47% FSD roll on the first try. Could be better, but I wasnt disappointed. I am using it now.

The blue and red bars tell you whether the roll is good or bad ...
Every further roll will even only tell you the difference to the already installed mod, so it´s even harder to keep an eye on the absolute percentage.
I stop when blue bars are short and red bars are long :D (and hopefully got some nice bonus effects)
 
Some people think that if you apply a mod into a fresh module (not enginereed one) you get better rolls most of the time.

No, it makes no difference.

Any roll is a fresh roll; if you apply the module, it replaces the old one. There's no 'stacking', or any effect on future rolls. You might get three great rolls in a row, or three rubbish rolls.
Its all RNG based on the ranges FD have set.

The graphs are the only thing that change on an already-modded roll - they show the relative chance that you're going to improve/regress.

I suspect confirmation bias also plays a part, especially if you only roll on clean modules and fresh instances now :p

Disclaimer: of course that doesn't mean you're not right!
