How to verify results when using Test from Spread

Question 1：The following are the input and output signals when using Test from Spread for testing. When input>3.7, output==true. But regardless of whether the input and output interp methods are linear or zoh, the output results are the same, equal to true at 3.35 seconds. What I hope is that at 4s, input=3.8, output==true, can I do it?

Question 2：Is it possible to use Test from Spread to verify the results at any time point like Test Sequence？
