How this is worked out

3 steps
  1. Projected weight = 10 x (1 + 10) / (125 + 10) = 0.814815 kg
  2. Age-1 reference weight = 10 x 11 / 135 = 0.814815 kg
  3. Age-100 weight = 10 x 110 / 135 = 8.148148 kg

Observed pet weight is linear in (age + 10), giving W2 = W1 x (A2 + 10)/(A1 + 10).

Roblox publishes the current DevEx USD-per-Robux rate; it changes, so the engine takes it as an input.
