updateInterval
From SAP Enable Now Wiki
Scope
Web Assistant parameter, specified either in the URL or in the Web Assistant parameters in the linked application.
Purpose
This property is used to specify how often Web Assistant should 're-scan' the application screen, to determine if help content is available. This is most significant for Help Tiles, where the hotspot/icon is displayed on the screen - scrolling too fast can result in them being very briefly mis-positioned. If the application is very fast, you may want to decrease this value. If the application only ever consists of single-screen pages, you can probably increase this parameter value and save some processing/network traffic.
Usage
Specified as:
updateInterval=[ms|100]
where ms is the number of milliseconds between refreshes.
