About Pokemon Yellow DV Checking
Pokemon Yellow uses DVs to shape each stat. DVs are early individual values. They range from zero to fifteen. Attack, Defense, Speed, and Special have direct DVs. HP is different. It is built from the lowest bit of those four values.
Why Accurate Inputs Matter
A clean calculation needs menu stats. It should not use temporary battle boosts. The level must match the stat screen. Base stats must match the species. Stat experience also matters. Older games track effort by stat experience, not modern effort points. Low effort often makes many DV sets possible. Higher effort can narrow the answer.
What This Tool Does
This calculator checks every valid DV from zero to fifteen. It compares the generated stat with your observed stat. It then joins valid Attack, Defense, Speed, and Special values. Each joined set creates a derived HP DV. The tool keeps only combinations that also match the observed HP. This gives a practical result set, not a single forced guess.
Using Results in Play
Use the range summary first. It shows whether a stat can be weak, average, or strong. Then review the matching combinations. A single row means the data is exact. Many rows mean more levels, more battles, or more stat experience details are needed. Rare Candies can help because they change level without adding effort.
Exporting and Recording
Save the CSV file when you want a spreadsheet record. Use the PDF file for simple sharing. Keep the species, level, and effort values with every result. That makes later checks easier. If a later level gives different ranges, update the inputs and compare again.
Best Practice
Check stats outside battle. Remove badge boost confusion. Enter known stat experience when available. If it is unknown, try zero first, then test likely higher values. The calculator is meant for careful checking, team planning, and classic save analysis.
Common Limits
Some inputs still leave wide ranges. This is normal at low levels. Small stat changes can hide several DVs. Trade evolutions and vitamins may also change assumptions. Record each change before testing again. Clean notes prevent mixed data. When unsure, calculate with conservative effort first. Then refine after more confirmed battles or levels.
