If using the 'GestaterEggScaleAdjustByDragWeight' setting then Gestater Eggs will rescale their size if the dino is outside of its kibble category's drag weight range.
Kibble Type Drag Weight Ranges are:

• Basic = 0-74
  
• Simple = 75-149
  
• Regular = 150-249
  
• Superior = 250-499
  
• Exceptional = 500-999
  
• Extraordinary = 1000+

For these examples we will use defaults:
GestaterEggScaleAdjustDiminish=0.9
GestaterEggScaleAdjustRate=0.66
GestaterEggScaleExtraordinary=0.7
GestaterEggScaleSuperior=0.5

We will use the Thylacoleo as example. Its dino kibble category is Extraordinary due to the kibble it prefers for taming.

Thyla Drag Weight: 180
Size of Kibble Category Drag Wgt Range: Abs(Max - Min)
Since Extraordinary has no max it is 0.
Extraordinary kibble category drag weight range 'size' is then: Abs(0 - 1000) = 1000

Since Thyla is smaller than drag weight Min for Extraordinary the egg will need to rescale smaller.

The algorithm for that is:
( 1 - ( (KibbleDragWgtMin - DinoDragWgt) / ( (KibbleDragWgtMin - DinoDragWgt) + (GestaterEggScaleAdjustDiminish * KibbleDragWgtRange) ) ) * GestaterEggScaleAdjustRate ) * KibbleCategoryDefaultScale = FinalScale

Thyla then is:
( 1 - ( (1000 - 180) / ( (1000 - 180) + (0.9 * 1000) ) ) * 0.66 ) * 0.7 = ~0.479744
So the egg for Thyla will be at roughly 48% scale rather than the 70% scale for Extraordinary Gestater Eggs.


For an example where the egg needs to scale larger we can use the Paracer.

Paracer Drag Weight: 600
Kibble Category: Superior
Kibble Category Range: Abs(499 - 250) = 249

The algorithm for that is:
( 1 + ( (DinoDragWgt - KibbleDragWgtMax) / ( (DinoDragWgt - KibbleDragWgtMax) + (GestaterEggScaleAdjustDiminish * KibbleDragWgtRange) ) ) * GestaterEggScaleAdjustRate ) * KibbleCategoryDefaultScale = FinalScale

Paracer is then:
( 1 + ( (600 - 499) / ( (600 - 499) + (0.9 * 249) ) ) * 0.66 ) * 0.5 = ~0.602522
So the egg for Paracer will be at roughly 60% scale rather than the 50% scale for Superior Gestater Eggs.
