No. It is there just for your information. It is nice to have an equipment with a high potential, but keep in mind that for equipments with multiple stats, you might be interested only in one or two, so these are the ones to watch out on tempering. You can always see the range on the preview page for tempering, if you get a very good number on this stat, it is generally better to keep the equipment as it is even if the other stats have minimum stats and the equipment has a low potential.
Tempering is random, a stat will increase or decrease within 30% (50 MA to anywhere within 35 MA to 75 MA), or within the full minimum and maximum, for certain equipments that have stats randomly created stats, such as specific MS boxes, for example.
