I did - try and try again!

After a shaky start I started blipping without a gap on 12 September 2012. I cringe as I look back on those early blips and I do feel I have improved a little over the year. Today the cobwebs are looking particularly beautiful especially this one on my front gate.
Can anyone tell me why my 'this time last year' blips don't show up? Is there some button I haven't pressed or were they so bad that they can't be shown - don't answer that bit?!
