I was once unfortune enough to have to get a boat off a shingle beach where she had bee neeped and with the wind in the direction it was she didnt float. So on the next tied I laid the main anchor and all the substatial (for her size) supply of chain accross the beach giving a scope acroos the muddy creek bed of about 50:1. when the tide got to the top all hand laid to both winches which rant to block and brough the cable bar tight and about middle 'C', you could see it visably thin. The boat however didnt budge so when the tied was down I walked round to recove the anch assuming it would be so well burried that it would need digging out. Imagion my suprise to frind that I had droped it on a sheat of ply sunk in the mud are there it sat high and dry, what had resisted all our efforts was 50m of 8mm chain and some sticky mud!
The moral, since confirmed many times, is that the cable is far more significant than the anchor. 5x for chain is ok in fair conditions but 7 times for rope is courting disater, and anyway why try to lay the minimum, lay out enoug heavy chain to garentee a good length is laying on the bottem and you wont drag. On my boat I use 2 45lb CQRs to give 90lb but then 100m 10mm chain which is about 500lbs! for a 6.5 ton boat
