Records with Random Chance of Loss

A new Record is created every 3 reloads of this page.   There is a 10% chance per reload for each Record to obtain a new Chance-of-loss Attribute.   There are 3 unique Attributes: Small (20%), Medium (50%), and Large (80%).   The percent Chance-of-loss is applied to a base 25% chance of loss per reload per Attribute.   Effectively, a Record with only a Small chance of loss Attribute would have a 5% chance to be lost per reload (20% * 25%).   A Record with all 3 Attributes would have 3 independent chances to be lost per reload: 5%, 12.5%, and 20%.   The Activity panel is styled using Bootstrap 3 default theme classes.  

Records that survived the reload, and were not lost, are highlighted in green.   Messages about Records are highlighted in yellow.   Records that are lost are highlighted in red

The Random Chance Mini-App uses Hashtag Markup to demonstrate an arbitrary non‑deterministic process.

Records are created on a reload count schedule, and randomly obtain negative attributes that can lead to the record being flagged as lost.

All records are stored in an SQL Database.
