@thunderkatt: I'm not sure if you've read and understood my comments on HRMs properly. But yes, there is a max limit to weight, size and age in YSFE 2012 (and in the original YSFE). I've tested the effects of these parameters earlier and only the weight adjustment seems to have a significant impact on the calorie count. Based on my weight of 80 kg, the calorie count in YSFE 2012 increases by about 1:1.54 when I set the maximum weight.
If you are NOT exercising in relation to other people, I see nothing objectionable in it, if you adapt your weight adjustment for improved calorie counting. Maybe this will help you to stay motivated and keep training. However, I doubt that the effect will last long. If you need a high calorie count to persevere, then I think your attitude to training is wrong. In defining and reaching your fitness goals, the calorie count should play no role whatsoever. No athlete defines the calorie consumption as a training target. Train hard, then you will be rewarded with better times and scores - and last but not least with greater fitness. This is definitely a better reward than a stupid calorie count.
The high calorie results of some participants of the monthly events are not solely due to the fact that they have set their weight to maximum. That would not be sufficient to explain certain results. Based on my experience and research I can say that in the last three monthly events there was hardly a conspicuous player under the top 20 who has not cheated. I will not go into details, but the lack of plausibility checks in the original YSFE and YSFE 2012 makes it possible, that these weaklings can easily surpass serious and committed competitors. This is a sad fact and it turns every monthly event sooner or later into a single farce.
