Before enabling the browse widget, set this attribute to the exact or maximum number of records you expect in the query. A more accurate setting of this attribute allows for a smoother and more accurate change in vertical thumb height when the user scrolls through the query for the first time. As a user scrolls through the records, the system continuously updates the value of this attribute with a better guess for the number of records. After all records have been read, the MAX-DATA-GUESS value is automatically reset to the exact number for more accurate browsing. The default value is 100.
