This sounds like a potential flash trading arbitrage play between code that implements the smear and code that doesn't. As in a whole bunch of market making institutions and retail traders are going to be a few hundred milliseconds slow off the mark that day? Speculating you may get a few extra tries guessing a PIN as well given the time based window shift, we might be able to see evidence of the drift in internet routing tables and back off penalties, the same might go for some buggy rate limiting implementations for web requests, where the number of requests you can get through in a "minute" will overflow a fixed integer value. I'm sure the blockchain DeFi people are already hunting through smart contracts for potential vulnerabilities on it. This is a really interesting problem, even if these ideas are speculative, it's where I'd go looking for vulns.
