支持在一台计算机上运行的Android模拟器/端口范围的最大数量是多少

基于此文档，您可以在5554到5682的偶数端口上运行多达64个仿真器

https://developer.android.com/studio/run/emulator-commandline
The default value is 5554 for the first virtual device instance running on the your machine. A virtual device normally occupies a pair of adjacent ports: a console port and an adb port. The console of the first virtual device running on a particular machine uses console port 5554 and adb port 5555. Subsequent instances use port numbers increasing by two — for example, 5556/5557, 5558/5559, and so on. The range is 5554 to 5682, allowing for 64 concurrent virtual devices.

但emulator cli的帮助却有所不同

emulator -help-port
  at startup, the emulator tries to bind its control console at a free port  starting from 5554, in increments of two (i.e. 5554, then 5556, 5558, etc..)  this allows several emulator instances to run concurrently on the same  machine, each one using a different console port number.
  use '-port <port>' to force an emulator instance to use a given console port
  note that <port> must be an *even* integer between 5554 and 5584 included.  <port>+1 must also be free and will be reserved for ADB. if any of these  ports is already used, the emulator will fail to start.

尽管亚洲开发银行的文档中有这样的描述，但我能够列出运行在5584之外的设备

$ adb devices
List of devices attached
emulator-5590 device
emulator-5690 device

我很困惑。虽然在5584之外运行模拟器对我来说很有用，但它是否受支持？我应该参考哪些文档？

另一篇stackoverflow文章让我看到了最近的一篇文章，似乎它们不再限制了，所以可能文档已经过时了。也在引用的“16个并发模拟器实例”中链接文档中不再存在。另一篇stackoverflow帖子让我看到最近的一篇文章，似乎它们不再限制，因此可能文档已过时。此外，引用的“16个并发模拟器实例”在链接文档中也不再存在。
