Well, Guinness World Records have declined to register my attempt as eligible for a World Record, citing,
"We receive over 60,000 enquiries a year from which only a small proportion are approved by our experienced researchers to establish new categories. These are not 'made up' to suit an individual proposal, but rather 'evolve' as a result of international competition in a field, which naturally accommodates superlatives of the sort that we are interested in. We think you will appreciate that we are bound to favour those that reflect the greatest interest."
Fair enough I suppose.
