HistoryTablet does not have set limit. But increase in number of entry will slow down some older iPhones.
Current Recommended Specification for limitation is as follow.
Events : 100
People : 100
Period : 1(with multiple periods inside a single period)
Time Span : 1000 Years
Time Span causes most strain on the device. With the latest phone almost 4000 year span on a single tablet was tested. It worked but performance was not desirable. Human history that we can document spans about 6000-7000 years and a single tablet can not capture the whole period with current engine.
On iPhone 12 Pro Max
600 events were used on 2200 year span without problem.
