"""platform_stat_display 增强:绝对增量增长 / 真实值偏移 / 只增不减护栏
|
|
|
|
给首页三统计配置加 5 列:
|
|
- random_kind ('mult'/'add') + random_step_min/max:自增长支持「绝对增量」(每周期 +[a,b]),不只是 ×倍率
|
|
- real_offset:真实值模式基数偏移(展示=真实+偏移,冷启动既真实又体面)
|
|
- allow_decrease:门面数字默认「只增不减」,开此开关才允许展示值下降
|
|
|
|
Revision ID: pstat3growth
|
|
Revises: marquee_seed02
