I've done a lot of research into economies at the time and if we use Germany as the baseline then the USSR's economy should be about on par with Germany's due to an increased reliance on agricultural and mining products which are on map resources. Germany had a much much higher per capita income representing the high quality and efficiency of Germany industry at the time. GDP per capita in Germany was $5125 while in the USSR it was about $2100 and per capita GDP in the UK and the USA was at about $6000 as of 1938 in 1990 US$ so despite the nominally higher GDP in the soviet Union it was much less industrial due to reliance on manpower heavy sectors like mining and farming and a generally poorly run and/or outdated manufacturing industry.Which leaves US some 100 factories short of actual World% in 1936. USSR some 20-40 factories short. The naval dockyards also seem to be all over the place.
This was my understanding of The Scientist Haven too but it wouldn't be nonsensical to give the USA an extra research slot considering the countries large and mostly well educated population.I think there is a mistake in the wiki made by someone like you who thinks a beaker picture is automatically an additional research slot.
The Scientist Haven focus is probably science related, but not an extra research slot as the other one is clearly labelled "extra research slot".
