Brexit for Scientists

According to this report: https://royalsociety.org/~/media/policy/projects/eu-uk-funding/uk-membership-of-eu.pdf

The UK gives a lot of money to the EU (2007-13) £77.7B, of which £5.4B is allocated to Science Spending.  (6.9% of £77.7B)

The UK receives £8.8B Back from the EU from this science budget. Therefore according to Scientists, we should remain because we are better off. We don't want to lose our science budget.

BUT, this £8.8B is only 3% of the money spent on science in the UK. The rest comes direct from UK sources.

So If we came out - Brexit, and were able to double the amount that Science had had from the EU, say to £18B,  (23% of the 77.7B) The UK would still have ~£60B to spend on other things, like the NHS, any tax barriers to EU trade, or whatever.
