Re: [quicwg/base-drafts] Proposed fix for #3987 (#4071)

[Jana Iyengar <[e-mail]>]

@ianswett pointed out that the point here is not so much about including max_ack_delay, it is about using PTO values. Thinking about this, I agree. The idea here is to basically allow for the sender to retransmit the probe multiple times, and that happens on PTOs. Basically, I think what needs to be written is an explanation of the expression. My suggested explanation and text:

`6 x InitialRTT` ensures that the period is large enough for sending multiple PATH_CHALLENGE frames on initial timeout (with exponential backoff). `3 x PTO` ensures that _if the current path PTO is longer than `2 x InitialRTT`_  then we allow for the new path to be as long. If we want to clarify something here, that would be the point to clarify.
