Good question, and it's two separate things: one is a deliberate decision, one is a gap.
The deliberate part. On earnings I show a third line in the entry block: the ATM straddle against the stock's average past earnings move. I measured it on events yesterday and it doesn't transfer. Across the nine live event combos, that ratio runs 3× to 7×, against a 1.72 median on earnings. The reason isn't calendar randomness, it's that a one-week straddle prices a full week of ordinary sessions, and on earnings the gap dominates that price while an ISM PMI moves GLD about 1.1%. So the same number means something completely different, and published with the earnings thresholds it would read "expensive" on every line, permanently. It's absent rather than wrong.
The honest version would be a self-referential one — "event premium richer than X% of past cycles here", same grammar as the two lines above it. That needs the ATM straddle history per cycle, which I don't store yet. It's on the list.
The gap. You're right that the implied move is missing from the tile itself. On pre-earnings the move tile shows "Current implied move ±X%" alongside the historical average; on pre-events it only shows the historical. That's an oversight rather than a choice, and it's the cheaper of the two to fix.
Thanks for spotting it, the tile and the block are different questions and I'd conflated them.
