Even though the benefit of removing the cast here is minimal, removing it still seems better as it won't need to be suppressed later if we decide to enforce the rules as part of the build.  In this specific case, there was no obvious way to "break" the code (by losing precision) by changing something unrelated (like changing `ptSize` to `double` or `long`).

Yes, this is OK.
