Hi! That is a healthy weight; so no worries in that respect!
Please be aware that Gizmo is starting to come to the end of the initial fast growth phase, so just look out that there is no weight loss, but don't necessarily expect a regular weight gain every week. The last part of the teenage growth comes usually in the occasional spurt rather than some steady growth.
It is useful to not just check the weight, but also the heft of a piggy, i.e. the ratio of weight to size, since regular weights and sizes can vary so enormously. That also helps to figure out whether a piggy is overweight or not. You do that by feeling around the rib cage, as the bum shape is genetically determined and not an indicator of overweight.
This link here tells you exactly what to look out for:
The Importance Of Weighing - Ideal Weight / Overweight / Underweight
Most healthy adult piggies swing around plus/minus 50g of their stable adult weight from their 2nd-4th/5th year of age. Once they get older, they tend to lose some and become a bit more bony (you can especially start feeling the hip bones).
