In this case, the two experiments interpret the same codepoints in the

A mail-sending domain indicates that it is participating by publishing
certain DNS RR's.
Crucially, a mail-sending domain cannot opt in to the SPF experiment
without also opting in to the senderid experiment. This renders any
claimed results of either experiment suspect.
If this is the source of the conflict, then BOTH experiments should
not use the v=spf1 records.
