No, it isn't, speed do not allow you to resist time stop:
1. Infinite speed is a speed that it so fast that time is frozen in the perspective of the character who perform infinite speed, but time not really stop, it is just the characters is so fast that time to them is frozen.
2. Now come to Immeasurable speed, the reason you can "resist" timestop with immeasurable speed is because that speed beyond the scope of what normal time stop can affect, you aren't resisting timestop, but rather it is the weakness of timestop, there is still timestop that can stop immeasurable speed though. So you saying IP can resist timestop via sheer speed is wrong, and IP somehow both have sheer speed to resist timestop and resistance to timestop is contradicting
