Don't Jack with My Basals

I have difficulty with the acceptence of the numbers of basal /bolus ratio…if I sit in the car being driven to my app’t I need to put a temp basal of 165 percent in place…when I walk a lot ( as presently ; training for a half M ) I put my temp basal sometimes : 45 percent …I know a chap , who cycles for miles and miles and his ratio is NOT 50/50 …why not keep basals /bolus ratio if ultamitely the result is GOOD for YOU …or Excellent for that matter???.
Time to ask the writer, John Walsh of Pumping Insulin once again ?
