From Britain Votes, Sir JC's calcs, the %spread of Con/Lab seats at equal shares (Tory advantage of 28 seats, 293-265):-  More marginal seats for Labour but also more strongholds. the 80-100 to figure for Lab is not good, they need more in the middle of these spreads On the plus side for Labour these strongholds prevent their total collapse/replacement by another party of the left and also ensure a 'safety net' in v.bad years (1983). A wise leader/party would use these seats to bring talent into parliament.

Of course the workings of the electoral system in some elections may have changed the course of the ensuing parliament. I'd say 1950 as the bias denied Labour a working majority it might have expected from the cube law and which would have allowed them to carry on until the mid 1950s at least,1951 Conservatives get in with few votes than Labour, Feb 1974 similar to 1951 with Lab as the beneficiary, Oct 74 Lab get similar lead to the Tories in 1955 but a fraction of the majority setting up an unstable parliamentary situation until 1979.
Also 1992 a 7.6% Con lead giving only a 21 majority easily eaten away by defections and by election defeats and 2010 as in normal circumstances the Conservatives might have expected a majority from a 7.3% lead

My rather verbose thoughts on the reasons for changing bias election to election post war:
1945-Lab bias with out of date boundaries-noticeable smaller electorates. 1950-1959-Clear Con bias in all cases due to Lab piling up votes in safe seats but in 1950 to 1955 due to rural seats being allowed to be smaller and in 1950/1 turnouts lower in Con seats. Some Lab counteraction to bias due to lower turnouts favouring them from 1955 and lower electorates from 1959(also Lab domination in Scotland 1959-2010).1955 bias little less as lower swing to Cons in marginals 1964-mild Con bias due to lower turnouts in Lab and increasing constituency size variations. 1966-Lab bias due to similar reasons as 1964 though not as much as could have been in 1970 as Con vote much more efficiently distributed in 1970 than 1966 Feb 1974-Lab bias though notionals showed con bias-more efficient distribution of Lab vote and tactical voting depriving Con of some seats that might have kept them largest party. Oct 1974-Con bias-mild due to their vote being more efficiently distributed due to lower swings in Con/Lab marginals 1979-Lab bias-lower swings in Lab marginals,ageing of boundaries,lower swings to Con in seats with lower electorates 1983 and 1987-Con bias due to most detailed redistribution to date,Labour piling up votes in safe seats,3rd party votes in con seats-all partially offset by lower turnouts and lower electorates in Lab seats and 3rd party wins 1992-significant Lab bias due to wider gap in turnouts/electorates and bigger swings to Lab in marginals 1997-Lab bias more than in 1992 due to larger swings in Con seats and ongoing big gap in turnouts between Con and Lab seats plus more 3rd party wins at Con expenses 2001-Lab bias widened still further due to larger turnout drop in Lab seats, boundaries based on 1991 data,increase in 3rd party votes in Lab seats and drop in Con ones(due to less Eurosceptic votes in Con seats and increase in Lib dem/some far left votes in Lab seats),plus Lab holding on to marginals and getting swing in their favours whilst safer seats lost chunks of their majorities 2005:Reduction in Lab bias but still large due to some tactical unwinding or marginals swings favouring con for first time since 1987 2010:Reduction in Lab bias as Con knocks out Lab's efficiency advantage and do better than uniform swing though clear bias still there due to the other factors 2015-2019-flipped back to Con bias-incurred in first election due to Con holding on in marginals(often getting swings in their favour) reducing issues of 3rd party wins due to SNP wins at Lab expense and Con gaining Lib Dem seats.Maintaining the bias in latter 2 elections as Lab continue to pile up votes in seats they hold and also Cons gaining in old Lab heartlands which means Con vote now more concentrated in seats with less voters and lower turnouts.

Or, to put it another way: swings, roundabouts.
