Sound info Trace. I recommend regular (monthly) weighings to monitor your animals weight.I think a slow increase in weight is better longterm than letting her gorge on insects to fill her out quickly. If I'm not mistaken the chance of liver problems increases dramatically when they are power fed.
95 to 105 degrees will cook your veiled, for an adult f veiled try to keep basking temp around 82.It depends on cricket size, for sure. For a healthy adult female (say 1+ yrs) on the order of 25 adult crickets over a week (e.g., 5 crickets/day x 5 days/week) sounds about right, but it really depends. This is one of those many areas where observation is critical: if the animal is thin (underweight) it needs more food, and if overweight likely needs less.
Since this animal is underweight, I'd feed as much as she'll eat every day, making sure to provide adequately high basking temps (95-105 F) along with appropriate ambient temps (say 75-80 F in the coolest places) so that she can maintain appropriate body temperature, digest the food, and put on weight in a healthy manner. Once she reaches a healthy body weight, you can probably end up cutting back the food availability.
