Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

How tolerant are most real time applications to clock jitter?

 Clock jitter, or the variation in the arrival time of clock pulses, can have a significant impact on the performance of real-time applications. The tolerance of real-time applications to clock jitter depends on the specific requirements of the application and the sensitivity of the system to variations in timing.

In general, real-time applications that require high precision and accuracy, such as those used in scientific instruments or control systems, may have a low tolerance for clock jitter. On the other hand, applications that do not require such precise timing, such as audio or video streaming, may have a higher tolerance for clock jitter.

There are a number of factors that can affect the tolerance of a real-time system to clock jitter, including the type of clock used, the design of the system, and the type of data being processed. To ensure the smooth operation of a real-time application, it is important to carefully consider these factors and design the system to minimize the impact of clock jitter.
