As a newbie T2 I find this thread interesting to compare myself to, as I am still trying to work it all out - expectations, targets etc.  So today low was 4.9 before my evening meal and high was 7.2 2 hours afterwards.  Waking was 6.7. 
 I usually manage both waking and post-dinner figures a little lower, but have had spikes of up to 11 after eating a little.....lot....badly when first starting a month ago.  Average waking 6.2, average before lunch 5.0, average before dinner 5.7 and 2 hours afterwards 7.9 (average ruined really by 3 high measurements), , all over over a month.  Not really sure if these numbers are OK ish or not?
