I almost feel nervous posting this as I don’t want to invoke a collective wrath but, with reference to P-G’s comment “Photographic evidence is pretty sparse and low quality, but see here: Before-and-After Measurement Pictures”, I have often dwelt on this very issue.
Certainly there are some overwhelmingly obvious reasons why such photos would be uncommon but given the number of members here it really does surprise me that there are not more photos showing the before and after effects of PE. Please understand me - I am a believer and I can personally attest to a very small gain after one year of PE but I do sometimes wonder about such things as measurement error and wishful thinking perhaps being behind the innocent over-estimation of some gains.
Please don’t beat up on me. Again, I re-iterate, I am a believer - it just really does surprise me that there are not more of these photos. Then again, when I put myself in those shoes, there’s another really good reason why this might occur. I, for one, didn’t take before photos so it would be a little hard to contribute myself to the before/after collection. And I imagine most are like me. Hm, I’ve perhaps answered my own little query here whilst writing about it :)
