After playing around with the norm tables a little, I've concluded that:
1. VCI is a significant relative strength.
2. PSI is a significant relative weakness.
3. VSI may be a low estimate, as it results from a higher motor-free spatial reasoning score (VP) and a lower motor-involved spatial score (BD), suggesting that the same motor speed/coordination factors (or whatever else may have slowed her down) that manifested as lower PSI may have depressed the BD score. (I determined this from the most likely subtest scores to have resulted in the collection of index percentiles provided.) She's very young, so asynchrony may be able to explain all of the motor speed discrepancies.
4. Most of the achievement scores are actually statistically in line with her VCI, with the exception of Pseudoword Decoding and Numerical Ops, which are higher than predicted. Math Problem Solving is on the lower end of expectations, but I agree that it probably has been affected by her limited formal instruction in math.
