Am I guaranteed to have the original stat as an option when recalibrating my gear?

Recalibrating gear can be an expensive ordeal, especially when you find an item you want to keep but just want to potentially improve one of its stats.

I rerolled a stat that I liked but it's on the lower end of the spectrum of possible percentages. I want to try rerolling it again to see if I can get a better version of the same skill, but I'm worried I might roll a completely different set of stats that I do not want.

If I rerolled a stat on an item, will I always have that stat as an option? Or is it possible that I might roll all different stats?

e.g.,

Suppose I had an item that I rolled Scavenging 40% (of 40-60%). If I rerolled, am I guaranteed that I will see Scavenging (at any percentage) as an option?

When you re-calibrate gear, the first option is always to retain your original bonus; However, the bonus retains its original value. This is only useful in ensuring you do not loose the bonus, all together.

The Test

To confirm this, I did my own testing. I re-calibrated 10 different items, twice. I focused on the same set of possible bonuses, to make it easier to assess the numbers.

• Sticky Bomb explosion radius
• Mobile Cover damage resilience
• First Aid ally heal
• Smart Cover duration
• Pulse Critical Hit Damage bonus
• Ballistic Shield health
• Seeker Mine explosion radius
• Support Station healing speed
• Turret duration

The Results

I found that not only was the original bonus always an option, but it was always the first option, and always the exact same value.

Given only 20 re-calibrations were made, there is always the chance of getting lucky and always rolling the original bonus. However, the chances of the bonus also always rolling for the first option, and being of the exact same value, is very minimal.

Observations on upgrading the value of a bonus

I estimate that about 1 in very 5 re-calibrations gave the bonus as a second option. Given that you are trying to upgrade the value of the bonus, this is what you are trying to do. I also estimate that about half of these doubles also retained the same value, so only 1 in 10 provided a chance to retain the bonus at a different value.

This aspect would need to be explored further, across far more re-calibrations.
