If there are significant, unanswered questions about the extent and nature of Frank's cheating, the topic open and relevant.
Not needing an accomplice doesn't mean he didn't have one.
Who is most likely to have helped or known about Frank's cheating?
Using a string of paid strangers seems improbable (how would you find, train and trust such persons?).
And it's just hard to believe that over many years Frank's family were never on course to observe/support him.
Some poster here anecdotally related how their own family and friends didn't turn out, but they weren't Frank - he was high-profile and setting record after record.
Planning and execution behind Frank's cheating are impressive.
The bike(s) had to be acquired and transported. He may have used disposable bikes, but they still had to placed on course.
Frank could ride a bike over a timing mat sometimes, which you'd need a lanyard to get a chip reading - and he used one.
But Frank was also spotting and photographed running backwards on courses, so another way he seems to have cheated was to ride a bike close to a timing mat, dismount, approach the mat walking or jogging, perhaps seeming to be a spectator, waving the chip over it, then retreating back to the bike and repeat the process for the next segment .
He could do that solo, but would need to lock the bike up and unlock it (to ensure it'd be there when he returned).
Leaving the bike behind with an accomplice would be easier/faster. With an accomplice or accomplices, he wouldn't have had to retreat on course at all, or backtrack as far, if the guarding accomplice also moved the bike.
Depending on the course, you might mix both cycling and riding in a car as non-running ways of ferrying between timing mats.
TBH, while I suspect Frank had help performing, or at least covering up, his cheating, I personally don't care if anything else unfolds.
But to say there's nothing left to discuss or know isn't accurate.
There are people still trying to say his DQs were due to timing malfunction.
If you don't want to know answers to these sorts of questions, or don't want others to know, squelching the thread is the right thing.
