Bug reports, corrections and chart suggestions are all welcome — the maths especially. If a number looks wrong, it might be.
A chart that won't draw, a control that does nothing, or a layout that breaks on your screen. Your browser and device help a lot.
An expected-value line that doesn't match the odds, or a count that disagrees with the session table. Include the roll count if you can.
Something the site doesn't track yet — place numbers, come-out rolls, point cycles. Tell me what you'd read off it.
Questions the FAQ doesn't answer, or general feedback on how the tools read.
