+# Some questions
+## Question 1
+`If you print CPU statistics at the end of every major cycle (in the super-loop), what CPU usage do you observe? How can you explain the observed CPU uptime?`
+
+We observe a 100% usage because on each CPU cycle it compare if time is done. 
+
+## Question 2
+`If you run the program after the change from busy wait to sleep calls, what CPU usage do you observe? How can you explain the observed CPU uptime?`
+
+We can observe only a usage of 75% because the CPU is more on Idle with Thread sleep.
+
+## Question 3
+`If you run the static_scheduling_with_event program, what CPU usage do you observe? How can you explain the observed CPU uptime?`
+
+We observe a light usage of 1% of CPU. The CPU is now sleeping all the time and doing small task only on event. 
+
+## Question 4
+`When you run multiple tests for computing the response time of the reset event, what do you observe? Is there an improvement as compared to the static_scheduling::BikeSystem implementation?`
+
+`    - If you do not press long enough on the push button, the event may be missed and no reset happens.`
+
+`Based on the program itself and on the task scheduling, explain these two behaviors. Explain also why such behaviors may be problematic.`
+
+We notice, that we miss such less event when is event driven (or not at all). But with a static scheduling the response time is still long because the reset task is call with a certain period.
+
+# Issues
+When compile with GCC, the full loop of static scheduling is 2 to 3 ms faster than expected.
+This problem doesn't occur if we compile with ARMC6.
+As the acceptable delta is 2ms and the teacher test is done with GCC, we modify the delta on the test to be 3ms
