To generate 9.7s for men and 10.7s for women 200m requires a certain amount of power output over the required duration.
BC elite team marginal gains in other areas, such as bike stiffness, aerodynamics, technology, and any other variable, has not been objectively quantified to the general public, that I am aware.
BC have improved training methods and medical back up, that has improved recovery, well being physically and psycologically. BC elite program has not quantified the total amount of improvement this has made.
BC said improvements are down to marginal gains, which may seem reasonable on face value. The marginal gains have not been quantified to the general public objectively, so cannot be certain whether this has totally accounted for (one whole second in the 200m tt from amateur to elite) and whether this explains the extra power that has materialsed.
My point of comparison was that in 1997 the men's National record was a touch under 10.7 sec and we can consider that this was an amateur era in British track cycling. Yes, there may have been drugs in that era, as proven by one sprinter being caught. British track cycling now is an elite system. The men's 200m National record is now 9.7s. So we have a benchmark of one whole second. This benchmark is further objectified as the amateur record in 1997 was done on a new state of the art indoor wooden 250m velodrome, with double discs used.
I hope I make my point here clearly, where I ask for the 'gains' to objectively add up and to totally explain the improvements. If they do not then I remain sceptical.

Dear Sir Dave Brailsford,
I hope you can take a moment from your busy schedule to read through this public forum thread, where I have expressed concerns regarding the improvements made to the British track team and Sky team performances, given that we are now in an era of elite cycling.
As you state in the above video, we now have tangible measures that doping exists in the production of elite performances in sport.
On the subject of tangible measures, may I raise a question regarding your own marginal gains initiative, that of tangible and measurable evidence from you to explain the improvement in British track sprint cycling in particular.
The objective example I gave on this forum is quoted above, where I compared and contrasted the one second improvement from the 1997 men's British National 200m times 10.7 (now 9.7) and the women's times 11.7 (now 10.7).
The question is how have GB sprint 200m times improved by one whole second from 1997 to the present day?
This is a period of fifteen years, which is how long the GB elite program has now been in existence.
Please take a moment to reference the photo below of the Olympic men's sprint final in Barcelona, with photo finish timings. From this we can clearly see that each of the black lines running vertically represents 1/100th sec and that one whole bike length equates to just under 10 of the black lines, so a bike length of 1/10th sec is a significant advance in distance gain for such a short distanced event.
The improvements you have now made in my comparisons are ten times this distance - to equate to one whole second. So that is approximately ten bike lengths. On a 250m track this means that 1997 record man is ten bike lengths behind 2012 record man, when crossing the finish line.
To put this into layman's terms 1997 record man has had a dicking of a life time. Or to put it more succinctly he has been comprehensively beaten by the present day National record holder.
As I stated above, my comparison (10.7 to 9.7) is objectified further by both men's records having been done on double discs on a new state of the art indoor 250m velodrome.
My hypothesis, is that generously, marginal gains may have amounted to a half of a second. I invite you to disprove this hypothesis and leaves you to give tangible and objective measures of how the other half second has been attained.
Yours sincerely
