Simulate weekly Billboard 200 album equivalent units (SEA, TEA, Pure Sales), drop-off decay dynamics, and RIAA Gold/Platinum milestone pacing.
| Chart Wk | Weekly Units | Pure Sales | SEA (Streams) | TEA | Est. Rank | Cumulative Total |

Billboard 200 ranks albums by multi-metric consumption: 1 Pure Album Sale (Physical CD, Vinyl LP, or Paid Full-Album Download) = 1 Unit. 10 Track Sales (TEA) = 1 Unit. 1,250 Premium Paid Audio Streams or 3,750 Free/Ad-Supported Video/Audio Streams (SEA) = 1 Unit (roughly ~1,500 blended).
Blockbuster debuts experience steep Week 2 drops (often 50% to 75%) as dedicated superfan physical purchases clear. By weeks 4–6, pure sales taper off and long-term streaming catalog inertia governs the weekly hold, retaining 92% to 96% week-over-week for high-velocity hits.
In the United States, RIAA awards Gold at 500,000 certified units, Platinum at 1,000,000 units, and Multi-Platinum at each subsequent 1,000,000 increment. Streaming equivalents count toward RIAA certifications using standard on-demand stream conversion formulas.
The preset loads a representative blockbuster pop trajectory: ~295k opening week, settling into consistent 55k–65k weekly streaming volume by week 18. At week 18, it yields exactly 60,000 weekly units, 1,631,000 cumulative units, a #3 rank, and a peak of #1 for 2 weeks—matching the exact captured Billboard 200 tracking report.
SEA (Streaming Equivalent Albums) converts on-demand audio and video track streams of songs on the album into full album equivalents. TEA (Track Equivalent Albums) converts individual song sales (e.g., buying 10 individual songs from iTunes) into one album unit equivalent.
