Observed November 4,2026 Asia/Shanghai at https://calcbe.com/en/tools/weighted-random-picker/
Synthetic input one per line: V01 Aster | 5; V02 Birch | 1; V03 Cedar | 0.
Expand Advanced. Disable Auto draw. Merge off, seed off. Without replacement.
Request3, strict off, showzero off -> Draw -> requested field3/result2/Items3 Valid2 Total6 Errors0.
Enable Show zero; Draw -> three table rows but still2 winners.
Enable Strict; keep request3; Draw -> request error, empty winners and table; parsed input Errors0.
Keep Strict and showzero; request2; Draw -> two winners, zero row still visible.
Names synthetic; no live prizes/accounts/payment. Order can vary with seed off; compare counts/membership.
