No, we haven't because the five-year-old Credit Suisse article is a generalized model applied across the entire world, but obviously different jurisdictions have different construction standards, construction codes, and seismic requirements that can have a huge impact on what the 'optimal' affordability for a tower might be.
Secondly, in Vancouver and most other municipalities, taller buildings are looking for higher density than the prevailing zoning, so they seek a rezoning. In doing that, they offer additional public amenities, social housing or similar benefits. Those offset the lower land price per unit that the graph implies, so going up to 80 storeys doesn't reduce the land cost shown in Greater Vancouver in the way the 'model' Credit Suisse created would imply.
Obviously the theoretical model is using 'affordability' as a measure of how much it costs to build a tower. It doesn't mean the tower units will be any cheaper. As we know, the higher up the tower you go, the greater the price asked. So in this case 'affordability' really means 'developer profitability', not that your 58th floor condo will be a bargain.
