Cash-out EV is $777 on a $1,000 pack (-22.3% net after the ~85% buyback) — the average rip loses money.
Cash-out EV is $777.37, and the sample is precise enough to place it below the $1,000.00 price: the 95% range is $706.76 to $847.99, which does not include the price.
The typical pull (median) is $849 — most rips return less than the pack price; the EV is carried by rare chase cards.
Recent pulls are averaging 12.0% below where they were 7 days ago. That is what the last week returned, not a reading of what is left — Courtyard publishes no inventory. A drop this size is consistent with the better cards having been pulled, and also with an unlucky week.
20.8% of pulls meet or beat the pack price, across 53 indexed pulls.

Downside · bottom-quartile rip

−$313

1 in 4 rips returns ≤ $687 cash — covering 69% of the price.

Upside · top-decile rip

1 in 10 rips returns ≥ $997 cash. Both figures use the observed buyback ratio.

Log this decision:

Verdict is computed transparently from indexed pulls: cash-out ROI, median pull, 7-day trend, hit rate, and sample size. Redemption shipping (typically $16+) is not included — cards worth less than a few times the shipping cost are usually better instant-sold than shipped. Not financial advice.

02 / Pool signals

What's happening in the One Piece Diamond Pack pool

Lifecycle stage, health, and chase removals — read from indexed pulls, never guessed.

Recent pulls run 12% below the lifetime average — the observed pool is weakening.

DEPLETING

Recent pulls run 12% below the lifetime average — the observed pool is weakening.

Pro adds the Pool Health score and chase-removal impact.

Not observable: packs remaining, value remaining, and which chases are still in the pool — Courtyard publishes a pull feed, not inventory. We label those unavailable rather than estimate them. Everything above is computed from indexed pulls and EV snapshots; thin or stale data pulls the score toward neutral. Formula

Chase tracker

chase tier ≥ $5,000 · confidence 86%

No chase-tier pulls (≥ $5000) observed in the last 30 days.

Removals are facts; what's left is not. Each row is a unique graded card observed leaving this pack, so it is no longer in the pool — though a card can return after a buyback, which is why re-listings are flagged. We show no “chance it remains”: Courtyard publishes pulls, not inventory, so that number would be guesswork. Formula

Signal lifetime

SIGNAL Fresh · 1.6 h ago

Recomputed against pulls indexed in the last few hours. At the observed pull rate, half the evidence behind this read is replaced in about 22 days.

Half-life: Pro

Aged, not predicted. Half-life counts how fast new evidence arrives, measured from real pull timestamps — it is not a forecast of where EV is heading. We publish no EV-drift half-life because our snapshot history is still too short for a regression to mean anything. The seeded placeholder points this note used to warn about have been flagged in the database and excluded from every chart, trend and score, so what you see plotted is observed data. Note the headline EV is decay-weighted, so it reacts to new pulls sooner than this whole-sample horizon implies. Methodology

04 / Floor safety

One Piece Diamond Pack floor safety & buyback reality

The two ways average EV lies to you — how top-heavy the pack is, and what FMV actually converts to in cash — then which exit pays most.

In One Piece Diamond Pack, the top 2% of pulls account for 7% of all pulled value — low dilution. Value is spread fairly evenly across the pool, so the average is close to what a typical rip returns. The observed instant-offer ratio is 85% of FMV, which is the cash number every verdict on this page already uses.

Floor safety

low dilution

7% of everything this pack has paid out came from just the top 2% of pulls. Value is spread broadly across pulls, so the average sits closer to the typical rip here than it does on a top-heavy pack. It still sits above the median — check both.

Buyback reality

84.6% of FMV observed

Across 51 indexed pulls that carry a recorded bid, a $100 FMV pull cashes out around $85 if you instant-sell — in line with the platform's 84.6%. This is the figure every verdict on the site multiplies by.

Holding, listing, or physically redeeming can beat the instant offer — but redemption shipping (typically $16+) eats small wins.

Net exit value

51 paired pulls · 96% bid coverage · confidence 85%

Instant-selling the average (mean) pull here returns $796.98 — $145.08 below sticker FMV (15.4% haircut). That figure is the average of bids we actually recorded, not the platform rate applied blind.

Pro compares all three exits side by side, with the redemption breakeven and the value-by-value haircut curve for this pack.

Bids are recorded, resale is not. Instant-buyback figures are real offers captured at index time and can move. Redemption shipping starts near $16 in the US, is higher internationally, and is charged per shipment — batching pulls lowers it. We publish no resale estimate, liquidity score, or time-to-sell, because no such data is available to us. How buyback works

05 / Observed odds

One Piece Diamond Pack odds — observed, not posted

Reconstructed from real pulls, so it shows what has actually been coming out — posted odds can't do that. It is a record of pulls, not a count of what is left.

Across 53 indexed pulls, 20.8% returned at least the $1,000 pack price and 1.9% returned double or more; the single best recorded pull is $2,140.

Observed across 53 indexed pulls — what actually came out of this pack, independent of the posted odds. The 48h column shows tier drift: a falling green tier means fewer of the good cards have come out lately — which may mean they are running out, or may just be a quiet 48 hours.

Recent pool: pulls are weighted so newer ones count for more, the same basis as this pack’s headline, verdict and the budget tool. The 53 pulls behind the hit chance are unweighted either way, and the 85% buyback is applied to both. Averages describe many rips — any single rip can land anywhere on the distribution.

Bootstrap resampling of 53 observed pulls with the 85% cash-out applied. Every pull is drawn with equal probability, so this is an all-time average: it will sit below the headline whenever the recent pool has run better than the lifetime one, and above it when the reverse is true. It also assumes the pool doesn't change as you rip — for top-heavy packs the downside is understated once the grail leaves. Estimates, not financial advice.
