Hmm...no, technically you do not require an AP chart.

However, having a page as useful as AP chart does not seem harmful to me. And someday in the future, someone might create a character/verse which requires a calc, in which case you would need the chart.

To summarize: The chart is harmless at present, and may provide useful in the future. The way I see it, it's better to keep the AP chart.
